FRIENDS and family of a murdered teenager have been leaving floral tributes close to the scene this morning.

Dozens of mourners have been to see the spot at the Inglis Barracks site in Mill Hill where the 17-year-old, named as Marvin Henry, was killed just after midnight.

People living close to the site say they heard three gunshots around the time of the incident.

Friends have described Marvin as “popular” and “a good boy” and say they are shocked he has been killed.

Eleven people remain in police custody after being arrested overnight.

One friend, who asked not to be named, said: “We never expected anything like this to happen around here. It's not a bad area.

“He was not in trouble, he was not involved in gangs or any of those things. He was friends with everyone.

“The fact something like this has happened in such an everyday area where everyone hangs around is shocking. I do not understand it.”

One friend said he had just finished school and had been at the Pavillion Study Centre in Barnet.

Residents on the estate say there has been increased trouble in recent weeks with evidence of drug dealing and taking, with some saying they are too afraid to go out at night.

It is understood Marvin moved from the Grahame Park Estate to Mill Hill about eight years ago with his family.

One former neighbour, Ann Jordan, who lived opposite the family, said: “He was a lovely boy. It's a total shock. He was always very polite. They left Grahame Park to get away from this sort of thing.”
