Gang and youth violence has continued to fall since the Tottenham riots, according to official figures.

Data from the London Probation Trust showed there were 21 fewer incidents of grievous bodily harm and wounding among people between the ages of 10 and 19 from April 2012 to March 2013 than in the same period in 2010/11.

The trust used statistics from the Home Office showing there were 52 cases of GBH and wounding in 2012/13, a fall from 71 cases in 2011/12 and 73 incidents in 2010/11.

Chief Supt Victor Olisa, Haringey Police's borough commander, said he was pleased to see his officers' hard work paying off.

He said: “There has been a decrease in violent crime because of a combination of tactical arrests and taking preventative measures.

“I’m glad to see that crime is coming down, especially violent crime, and I fully expect to see it continue to fall.

“I think now there needs to be more work between the community and the police because officers cannot be everywhere at once so really do rely on people to report crimes when they see them and engage with us.”

Seema Chandwani, a youth worker, agreed with Mr Olisa but said the community had to prevent teenagers from turning to crime in the first place.

She said: “It’s really positive to hear that youth violence offences are down but more preventative measures need to be put in place.

“There needs to be greater partnership between schools, parents and community organisations to make sure young people are not put in a position where crime is an option.

“It is important that we have a working youth service and youth centres so teenagers have constructive activities to get involved in.”
