An investigation has been launched after a police car dramatically combusted into flames on the M6 near Preston.
Northbound traffic was held between junction 32 (Broughton) and 33 (Hampson Green), after the police car caught fire on the hard shoulder at around 9.40am yesterday (Wednesday, May 8).
Startled officers had swiftly pulled over onto the hard shoulder when smoke began billowing from underneath the bonnet.
Both officers managed to escape from the burning car unscathed, before fire crews arrived to battle the blaze.
According to a spokesman for Lancashire Fire and Rescue Service (LFRS), the officers reported feeling a "bump" from under the car as they were driving along the M6.
Minutes later, the police car had been completely consumed by fire.
