Officers from the Met’s Flying Squad stopped a vehicle in Gander Green Lane, at approximately 3pm yesterday as part of an armed surveillance operation.
The operation was organised as part of an investigation into a firearms incident in Carshalton on June the 17th.
A 40-year-old male and a 39- year-old female in the car were arrested on suspicion of possession of a firearm with intent to cause fear of violence, possession of an offensive weapon, and possession with intent to supply a class B drug.
The vehicle was searched, and police found a loaded air rifle.
The male suspect was also in possession of a knife and a large quantity of cannabis at the scene.
Officers later searched the male suspect’s home address and recovered a further four air weapons, 10 hunting knives, and a crossbow.
Both suspects remain in custody at Wandsworth Police Station.
Enquires continue.
