"Deep" concerns have been raised over knife crime in Greenwich after an 18-year-old man was stabbed to death.

The leader of Greenwich Council said the local authority is working hand in hand with the police to try and stop the spread of violence.

This comes after 18-year-old Aron Warren, who also went by the name of Aron Murray was found collapsed with stab wounds.

Aron is the 23rd teenager to be killed in London since the beginning of the year.

Officers were called to Topham House in Prior Street at 9.41pm on December 8 to reports a man had been stabbed and was unresponsive.

Aron was pronounced dead at the scene by paramedics shortly after they arrived.

Tributes on Facebook and Twitter say Aron was always happy and would help anyone who needed it.

One said: "The amount of times you can chill with someone, have them stay round your yard, share memories with them then all of a sudden they become another statistic on a spreadsheet showing how many people die by knife crime, the anger is so real this wasn’t meant to happen man."

Another said: "Wow can’t believe I’m saying this but RIP Aron Murray, remember when you jumped from that container broke your ankle and walked off like nothing happened.. only to see you next day with a cast and crutches.. real always go too soon."

And a woman on Facebook said: "Rest in perfect peace Aron we all miss you so much! Love you loads. Fly high Irish."

Councillor Dan Thorpe, leader of Greenwich Council, said: “It is tragic to lose another young life. The council is deeply concerned about knife crime and is working with our communities and the police to do what we can to stop the spread of violence."

Cllr Thorpe continued: "Just last week, we met with members of our faith community to discuss and review our approach, and are planning an event for young people early in the new year. We are working hand in hand with the police to provide any assistance that they need.”

An investigation has been launched to determine what happened in Topham House and who is responsible for the death of the 18-year-old.

A 17-year-old boy was arrested in connection with the incident but has since been released with no further action.

Met Police commissioner Cressida Dick has insisted the tide is turning against the rise in violent crime.

She told LBC that after three years of gun and knife crime increasing, the rate is now starting to level off and come down.

But she admitted it would take a long time to tackle the 180 violent gangs in London that are "busy" dragging children into crime.

Figures released by Scotland Yard showed that in September, October and November this year there were 176 fewer victims of knife crime with injury aged under 25 than in the same three months in 2017, a 31 per cent reduction.

Over the course of a year, there has been a drop of 287 victims, a 13 per cent decrease.

Police are appealing for witnesses and those with information about the Topham House stabbing to contact them on 101 quoting CAD 7621/8Dec or calling Crimestoppers anonymously on 0800 555 111.
