A man and two teenagers have been arrested by police investigating a shooting at a barbecue.
Four people were injured when up to five men “indiscriminately” fired a weapon into a large crowd during the event in Clarence Gardens in Camden, north-west London, on Saturday.
Officers arrested a 22-year-old man on suspicion of possession of a firearm with intent on Tuesday, while two boys, aged 16 and 17, were arrested on Wednesday night.
The 16-year-old was arrested on suspicion of possession of an offensive weapon and robbery, as well as possession of a firearm with intent. The 17-year-old was held on suspicion of possession with intent to supply and possession of a firearm with intent.
Shots were fired into a group of people attending the communal barbecue near Regent’s Park just before 10.10pm on Saturday, the Metropolitan Police said.
Firearms officers were sent to the scene, along with paramedics.
The injured – a 19-year-old woman, a 17-year-old girl, a 28-year-old man and a 73-year-old woman – were taken to hospital.
One was later discharged and the others are not thought to be in a life-threatening condition.
The Specialist Crime North Reactive team is investigating the incident.
