On Saturday (13 June), at about 7.30pm, officers from North Yorkshire Police’s Operational Support Unit and Roads Policing Group spotted a suspicious vehicle on the A1(M), near Boroughbridge.

They followed the Mercedes C200 and brought it to a stop south of junction 44 at Bramham and discovered around £10,000 inside the vehicle.

Officers carried out a roadside drug wipe on the driver, a 60-year-old man, and he was arrested on suspicion of drug driving and money laundering.

He was later charged with failing to provide a specimen of blood for analysis, and released under investigation while enquiries continue into the suspected money laundering.

Meanwhile, a second car travelling near the Mercedes, a VW Golf, left the motorway at junction 46. Officers located it at the service area there.

The 26-year-old driver was arrested on suspicion of drug driving, possession of cannabis and money laundering.

He has been charged with failing to provide a specimen of blood for analysis, received a cannabis warning for possession of cannabis, and released under investigation while enquiries continue into the suspected money laundering.

Both vehicles were seized for further examination.
