A house in Colliers Wood was raided this morning in a police operation to tackle suspected gang members.
The house on Boundary Road was raided at around 8.30am by several officers as part of Operation Valiant.
An eyewitness tweeted: "Heard a bang, looked out & there were 6-8 police + dog."
They also said there were police community support officers on nearby roads.
They added: "It's a lovely street with many families & loads of young professionals. Still, crime can happen anywhere sadly."
It was one of a series of raids taking place across London as part of the operation.
Operation Valiant is being run by the new Trident Gang Crime Command, a Met Police initiative which aims to tackle gang crime including assault, robbery and drugs supply across London.
