A motorist allegedly “threw a beer can out of a car window” before a crash on the M25, leading police to arrest a man on suspicion of drink driving.

Officers were called to junction 2 of the M25 following a road traffic collision and reports of “bad driving”.

Shortly before the crash, a member of the public reported seeing the suspect vehicle, a Subaru, being driven erratically and the driver is said to have “thrown a beer can out of the window”.

The crash, which happened at around 7.00pm on Sunday December 19, involved two cars.

One of the drivers is reported to have left the scene before police arrived.

Officers searched the area for suspects.

 A man was located near a petrol station in Hawley Road, Dartford.

Police say a man was reported to have failed a roadside drugs test and he was arrested on suspicion of drink-driving, driving under the influence of drugs, and failing to stop at the scene of a collision.

He has been released under investigation whilst enquiries continue.
