As many as 800 young people crowded a central city street during the London Marathon, drinking alcohol and inhaling nitrous oxide, according to a new police report.
A pram was tipped over amid the melee, details of which have emerged as authorities plot how to prevent a repeat of the incident. The new report reveals police recorded anti-social behaviour by up to 800 youths in the Byward Street area on 22 April during the marathon, adjacent to the Tower of London leg of the route.
The report on the incident was provided to the City of London Corporation public safety committee this morning.
City of London Police's Superintendent Lee Presland told the committee he ran this year's marathon and had noticed a change in the atmosphere.
He said: "You actually picked up a different vibe at that point, some quite nasty comments, which is not perfect."
The crowds had no interest in the actual marathon, he said.
The report said the incident resulted in four arrests for assault, and extra officers had to be sent to the area to disperse the crowd.
A Lake District charity says many young people will benefit from the money that's been raised in honour of a Cumbrian chef.
The Masterchef finalist Matt Campbell (pictured) collapsed during the London Marathon and later died.
He was running to raise money for the Brathay Trust and the total on his online fundraising page has now reached more than £350,000.
The trust helps young people, often from troubled backgrounds, through outdoor experiences and confidence-building training and the chief executive Godfrey Owen says a lot of thought must go into the way so much money, raised in 55 countries, is spent.
We'll be making sure we communicate exactly how we spend the money and really thanking those people who have contributed."
The organiser of a run in honour of MasterChef contestant Matt Campbell, who died after collapsing near the end of the London Marathon, says the interest has been "beyond crazy".
The 29-year-old was taken ill at the 22.5-mile mark and died in hospital.
Matt Dorber, from Street in Somerset, launched the "Finish for Matt" campaign which has since gone viral.
Thousands of people across the world have now taken part, running the 3.7 miles Mr Campbell could not complete.
