A teenager boy has been stabbed while walking with his mother in Hackney.
The 16-year-old victim was surrounded by a group of youths following a verbal "altercation", after another male in the group threw a glass bottle in the victim's direction, which missed him and smashed nearby.
A fourth male rode up behind him on a Barclays hire bike in Murray Grove and stabbed him in the back.
The group ran off in the direction of New North Road on Tuesday, November 19, the Hackney Gazette reported.
The victim was taken to hospital where he was treated for a single stab wound before being discharged.
Police have now issued an appeal for witnesses.
The suspect riding the bike was a black male, about 17-years-old, tall and slim. He was wearing a dark tracksuit with the hood pulled up.
