"It was assisting some patrol units and detectives in attempting to locate stolen vehicle that was being driven erratically," he said.
"We were lucky enough last night that the chopper was available and could come up (from Melbourne). It is another enforcement tool for us."
Senior Sergeant Brooks said the stolen car had been seen around Bendigo in the last couple of days.
"The public has been good in letting us know where the car is but the people (in the stolen car) are just refusing to stop," he said.
"The aerial platform is able to follow (suspects) safely and reduce the risks of them hurting trying to get away."
