The car was stopped on the M74 on Saturday evening and searched by police with dogs, Police Scotland said.

Officers recovered heroin with an estimated street value of £7,000 and cocaine with an estimated street value of £3,000.

The lamb has been taken in by a local farmer while police continue to work to establish why it was there, the BBC reports.

The three occupants of the car – two men aged 52 and 53, and one woman aged 38 – have been charged with drugs offences.
