Police discovered a large-scale cannabis factory as they busted addresses across south London, seizing a suspected firearm at dawn.

Firearms warrants were executed at eight residential addresses in Croydon and Bromley this morning.

Three men and two women, aged between 21 and 55, were arrested on suspicion of offences including possession of a Class B drug (cannabis) with intent to supply, cultivation of cannabis, money laundering, theft of a motor vehicle and firearms offences. 

Officers also recovered a stolen BMW and a motorbike. 

The large-scale cannabis factory was found on Alexandra Crescent in Bromley.

Superintendent Andy Brittain, from the South Area Basic Command Unit, said: "In the very early hours of this morning, Met officers carried out a number of warrants at residential properties in the Croydon and surrounding areas where we suspected firearms were being stored.

"Following searches of the properties, we have discovered a cannabis factory and arrested five people.

"Today’s warrants are a continued commitment to tackling shootings and violent crime in London that leave victims seriously injured or dead.

"No matter what the hour, Met officers are out on the streets making arrests and seizing weapons that are intent on causing serious harm to others."
