A 20-year-old man has been arrested on suspicion of the murder of a teenager shot dead earlier this week.
Mohammed Hussein, 19, was found collapsed in Bounces Road in Edmonton, north London, at around 9.45pm on Monday.
A post-mortem examination found he died of a shotgun wound to the chest.
Today police said a 20-year-old man was arrested on suspicion of murder yesterday, and remained in custody today at an east London police station.
A spokesman said officers are keeping an open mind about the circumstances of the incident and any motive.
After Mr Hussein was shot, neighbours ran to help and paramedics battled for half an hour to save him before he was pronounced dead at the scene.
Jordan Simbananiye, 18, said on Tuesday: "They spent about 20 or 30 minutes trying to resuscitate him but then after about half an hour they put a blanket over him.
"Blood was just pouring out of him - it was shocking."
