Arson Squad detectives are investigating a marked police vehicle being deliberately set alight in the early hours of Friday, 1 July 2022.
The police vehicle was parked on the forecourt of a vehicle dealership, located on Anstruther Road near the intersection of Pinjarra Road in Mandurah.
About 4.30am, two people approached the dealership on foot and poured an accelerant over the vehicle, before igniting it with a butane torch. The police vehicle was extensively damaged by the fire and is not repairable.
It is believed one of the offenders may have suffered burn injuries to their face and arms.
