Portsmouth 'hammer attack': New CCTV pictures released
Police have released further CCTV images of a man they want to trace following a suspected hammer attack on a 17-year-old girl in Portsmouth.
An attempted murder investigation was launched after the attack at a property in Shearer Road on 11 April, which left the teenager with "life changing" injuries.
Police called it a "vicious attack".
Hampshire Constabulary carried out a reconstruction of the attacker's movements on Saturday.
The attacker is described as a white man, of small to medium build, about 5ft 5ins (1.65m) tall, with short light-brown hair and a short beard.
A £5,000 reward for information that leads to a successful prosecution has been offered.
Officers have said the girl's injuries were believed to have been caused by a hammer.
Det Chief Insp Liz Williams said: "We have had a very positive response to our appeals for information so far but we are continuing to use every opportunity to engage with the community to identify this man.
"We believe someone knows who he is and I would urge anyone with any information to come forward."
Officers are also investigating whether the address was targeted due to links with the sex trade.
Chief Insp Jim Pegler said: "We understand people may be nervous about contacting police.
"We also understand that people involved in sex work may be concerned about their safety and wellbeing and there are agencies they can talk to other than the police if they want advice."
