Two Swindon men were arrested in Penhill after stolen cars crashed while racing on Thamesdown Drive and police seized £3,000 of class A drugs and £1,000 of cannabis from garden sheds.

Officers travelling in an unmarked police car on Great Western Way on April 21 were overtaken by a speeding black Audi SQ5 which raced a Skoda Yeti when it reached Thamesdown Drive.

Both vehicles were believed to be stolen and driven on false number plates. Police saw the Yeti crash into an electricity station in Emerson Close, and the Audi crashed nearby.

Five men got out of the vehicles and ran through an alleyway. After investigating, police visited two addresses on Thursday, where they arrested the pair and seized the drugs.

A 19-year-old was arrested on suspicion of aggravated vehicle taking and possession with intent to supply class B drugs. An 18-year-old was arrested on suspicion of aggravated vehicle taking, possession with intent to supply class A drugs and possession of class B drugs.

They were taken into custody and have since been released under investigation while enquiries continue.

Det Supt Steve Kirby leads Project Optimise, the force’s collaborative response to serious and organised crime.

He said: “Proactive officers have been conducting extensive enquiries since this initial incident and have been able to identify two individuals who we have since arrested in connection with the incident.

“While in attendance at their separate addresses, cannabis was found in the garden shed of one of the addresses, while a number of wraps of suspected class A drugs were found prepared in a shed at the second address.”

Anyone with further information in connection with the incident should call 101.
