Sex offenders 'facing a lack of rehab and monitoring'
BBC South West Home Affairs correspondent
A child sex offender who’s recently been released from prison and is looking to find a home in the South West, says chaotic living arrangements and a lack of help have increased the risk of him reoffending.
There are also concerns about the level of monitoring by the police.
A freedom of information request by the BBC revealed that each specialist officer in Devon and Cornwall has been assigned 60 sex offenders - when national guidance recommends a maximum of 50.
Diane Wills is from the South West charity, Circles...
The government says it's spending £6m helping vulnerable former prisoners find stable accommodation.
Devon and Cornwall weather: Dry and sunny with showers
We definitely need to work more closely together as different organisations...but I also think that we need to support general practice around intervening earlier. We are fortunate in Cornwall that people are living longer, but they do have a multitude of health and social care needs, and we need to support people in communities to look after their own. It's not that there's anybody to blame, we're probably just not moving fast enough to keep up with the people who need looking after."
People are being urged to seek advice from their GP, pharmacist of the NHS 111 service.
Patients can also visit one of the local minor injury units at Bodmin, Falmouth, Redruth, Launcester, Liskeard, Newquay, St Austell, St Mary's, Stratton, and Bude, or the urgency treatment centre at West Cornwall Hospital, Penzance.

BBC Radio Cornwall
Cornwall's main hospital says it is still dealing with a critical incident on Wednesday evening as it struggles to cope with "extreme pressure" on services.
Medics have been asked to step in to help after the Royal Cornwall Hospital, near Truro, declared the incident.
It came after 15 ambulances were observed queued up outside the hospital in Treliske on Monday.
The hospital has seen increased pressure on services since April.
Prime Minister Theresa May said the government was "aware of issues" after local MP Sarah Newton told the House of Commons of the situation.

Stadium for Cornwall deal 'in touching distance'
Local Democracy Reporting Service
Deals to provide the land and government funding
required for the Stadium for Cornwall are within “touching distance” and could
be signed by the end of this month.
That's the message from Bob Egerton, Cornwall Council Cabinet member for planning and economy, who told a full council meeting he believed there would be a "happy outcome" for the long-awaited stadium.
The Stadium for Cornwall is planned to provide a new home for the Cornish Pirates rugby union team as well as for football side Truro City. It will also provide conference facilities, space for Truro and Penwith College and a gym, as well facilities for other sports clubs and community groups.
It is planned to be built at a site next to the park and ride at Langarth near Threemilestone.
Last year Cornwall Council agreed to provide £3m towards the project but only if that was matched by the government, fulfilling a promise that had been made by former Prime Minister David Cameron.
Conservative Councillor Philip Desmonde asked for an update and whether the deals for the stadium had been completed and whether landowner INOX was in a position to hand over the site.
Independent Mr Egerton said INOX had been set to hand over the site for the stadium as part of a Section 106 planning agreement linked with the major housing and retail development for the surrounding site.
However, the agreement was that the stadium site would not be transferred until the developer had started to build homes, adding: "We are in touching distance of not just getting the memorandum of understanding but the legal transfer to be signed off."
South West Water 'on track to cut pollution incidents'
Cost of agency staff hits hospitals after increases
Health Correspondent, BBC Spotlight
The cost of agency staff has rocketed at many hospitals in Devon and Cornwall, with levels now far higher than in 2014 and 2015, before measures were first introduced to reduce them.
The big spenders are the Royal Devon & Exeter, which spent just over £11.5m last financial year - its cap was £8.7m.
The Royal Cornwall Hospital spent £9.3m - more than 50% higher than at its original peak - with Torbay and South Devon spending roughly the same.
On the other hand Northern Devon Healthcare and University Hospitals Plymouth both reduced their spend considerably. Unfortunately there was no one available for interview to tell us how they had achieved that.
Agency staff use matters because it's more expensive to buy in agency workers than pay for staff and NHS finances are already tight. Agency workers may also be less familiar with the teams they are working in.
Demand for services is rising at a time when it is becoming increasingly difficult to fill jobs, particularly in nursing. Brexit may be making the UK less attractive to some European workers.
The Royal Devon and Exeter Trust said its priority was to maintain safe staffing at all times and that it had taken a series of actions to do this, including national and international recruitment, better conditions for temporary workers and reducing turnover rates.
The Royal Cornwall Hospital Trust also said it was trying to reduce such costs.
The alert has been called at the Royal Cornwall Hospital near Truro to deal with the high levels of demand, with requests put out to Cornwall Council and the Cornwall Partnership Trust to help resolve the situation.
ED consultant Andy Virr admitted that, during Monday's situation, "for most patients the experience was poor in terms of being in a corridor, but we made every effort to make sure their treatment started in a timely way".
We don't want to see patients in corridors which is why we have done what we have done today. But last night [Monday], it was on the edge. It was very difficult and required a whole team effort to make sure that no patients were going to come to harm."
It was a very worrying situation. I certainly saw one patient that had spent nearly four hours in the ambulance in the ambulance bay and that's a terrible situation."
Health bosses are urging people to use minor injuries departments or call NHS 111 before visiting the hospital.
Major incident declared at Royal Cornwall Hospital
BBC News Online
A major incident has been called to deal with the high levels of demand at the Royal Cornwall Hospital (RCHT).
This means RCHT is working with Cornwall Council and Cornwall Partnership Trust to focus on and resolve the current situation.
Last night the hospital was put on black alert when patients were being treated in corridors and up to 15 ambulances were waiting for beds to become available.
Emergency Department consultant Andy Virr was on duty and said: "It was a very worrying situation. I certainly saw one patient that had spent nearly four hours in the ambulance in the ambulance bay and that's a terrible situation."
He added: "A major incident gives permission to ask all the leaders of the organisations to clear their diaries and come together to work hand in hand to free up community hospital beds, to access packages of care to get patients home and to get extra transport home - all the things that need to be done. They are also asking staff - NHS nurses and doctors - to see if they can work extra hours in the next few days to make the situation safe."
Council forced to adjourn meeting after protesters' heckle
Local Democracy Reporting Service
Cornwall Council was forced to adjourn a full council meeting on Tuesday morning after protesters refused to stop shouting in the debating chamber.
The council was meeting in Truro and there had been a protest beforehand about over-development in Cornwall.
Under the full council agenda there is time set aside for public questions but these needed to be submitted in advance and sent to the council by last Thursday. When it was announced there were no public questions, some in the public gallery started to shout down into the chamber.
Council chairwoman Hilary Frank tried to explain the procedures to the protesters but was drowned out by shouting. She then said she would have to adjourn the meeting and ask people to leave if they did not stop.
Council leader Julian German then stood up and explained the procedure. He said he was sorry if people did not realise the protocol but said that it had to be followed as part of the council’s constitution. He then said that full details of how to submit questions would be sent to people who wished to so they could do so in the future.
Ms Frank then adjourned the meeting and the webcast was turned off while the situation was resolved. Protesters started to then slow clap in the public gallery.
Security staff started to ask people to quieten down or leave and Mr German then came into the public gallery to speak to the protesters and explained that they were welcome to stay but would have to remain quiet so that the meeting could continue.
Eventually the protesters left the public gallery peacefully. Within minutes the meeting was back under way.
Ms Frank thanked the public for attending and said that it was important the council listened to their views.
Protest against 'destruction' of Cornwall
Local Democracy Reporting Service
Dozens of protesters have been at County Hall in Truro to call on Cornwall Council to help prevent over-development.
Banners and chanted slogans on display including "need not greed" as councillors walked in ahead of a full council meeting. There were also outbursts of the unofficial Cornish anthem, Trelawny.
They claim Cornwall Council is not doing enough to prevent the over-development of sites across the county.
Cornwall Council leader Julian German and cabinet member for housing Andrew Mitchell both came out and spoke to the protesters.
Cornwall Councillor Andrew Long, deputy leader for Mebyon Kernow, said the protest was "excellent".
But he added: "They should be targeting it to the government. Not just the Conservative government, the planning policies that we have to follow are a result of the coalition government and the previous Labour government so they are all responsible.
"The policy now states that building is a golden thread which runs through the planning policies. In the past developers had to prove a need to build, but now they have to prove why there isn't a need to build."
Every time I drive through I see another estate - the houses are substandard, who lives in them? Where do they work? How do they get a doctor? It staggers me that this over development is being allowed to happen."
