Detectives from the Western Region Crime Squad arrested two men and a woman after two police vehicles were rammed in Mount Clear on Wednesday night.
Officers observed a silver Ford Falcon drive into a car wash facility on Geelong Road about 8.50pm.
Checks revealed the Ford was stolen from Torquay in September 2023 and was bearing false registration plates.
Two police vehicles parked in front and behind the Ford with their lights and sirens activated, when the driver of the Ford allegedly began ramming both stationary police vehicles.
Two offenders were arrested at the scene and the driver fled on foot but was arrested nearby.
A homemade shot gun was located inside the driver's side door and a fold out knife was located on his person.
Three police members received minor injuries as a result of the collision.
The driver, a 20-year-old Wendouree man, was transported to hospital with minor injuries and is currently under police guard.
A 43-year-old Eureka man and a 35-year-old Eureka woman are currently assisting police with enquiries.
The investigation remains ongoing.
