Three people have been injured after a gunman opened fire outside a north London tube station on Monday night, police have said.

Officers were called to reports of gunshots outside Kingsbury underground station shortly before 10pm. Scotland Yard said it was waiting for a full assessment of the victims’ injuries, but a spokesman indicated they were not thought to be life-threatening.

The incident, which police are not treating as terror-related, was the second reported shooting in the capital that day, the first having taken place in the Kilburn area of north west London. There is no indication they are related, though investigations are at an early stage.

The latter shooting took place in the Brent area of north London. “Police and LAS (London ambulance service) were alerted at around 9.45pm on Monday 20 August to reports of shots fired in Kingsbury Road, NW9,” officers said.

“Officers from Brent attended the location along with London ambulance service.

“They found three people suffering injuries. We await assessment of their condition. A crime scene is in place and local roads are closed. There has been no arrest at this early stage.”

Referring to the earlier incident, police said: “Officers were called [on Monday] evening to reports of shots fired in Kennet Road, W9. No one was found injured and the suspects left prior to police arrival. A search of the area took place. Enquiries are ongoing into the full circumstances of the incident.”
