Police shot out a car's tyres before arresting two passengers over alleged firearms and drugs offences.

Officers armed with shotguns used tyre deflation rounds to disable the vehicle's back wheels during the operation on Wednesday.

The vehicle is not believed to have been involved in a pursuit prior to the incident, which police described as "intelligence-led".

A 32-year-old man was arrested at the scene in connection with alleged firearms offences, along with a 38-year-old man who was arrested over alleged drugs offences.

Meanwhile, a police watchdog is investigating claims that guns were pointed at the men as they were detained in Carfin, near Motherwell.

The Police Investigations and Review Commissioner (Pirc) examines every police incident involving firearms.

The Pirc said: "It is reported that the rear two tyres of a vehicle were damaged during the incident after the rounds were discharged by specialist firearms officers with shotguns, but no members of the public were injured.

"It also alleged conventional weapons were pointed at the occupants of the vehicle while being detained by police.

"The firearms discharge occurred following a police operation."

The Pirc is expected to report its findings to Police Scotland.
