Two police officers have been suspended with pay, and one will be charged with drug offences, following a pursuit in Melbourne's CBD.
Police tried to stop an unregistered car on William Street in the early hours of Saturday morning.
However the car drove away, running a red light before stopping in Bourke Street.
The five people who were in the car then fled on foot.
Officers from the Public Order Response Team arrested a 28-year-old man who was identified as an off-duty officer from the North West Metro region.
The senior constable is expected to be charged on summons with drug possession, police said.
A second off-duty officer who had been in the car was also located.
The 28-year-old, a recruit, was "spoken to in relation to the incident" and was suspended with pay.
Detectives from the Professional Standards Command are investigating.
