There are five people in custody assisting Warrnambool police after a series of police chases and divi van ramming which covered an area from Colac to Port Fairy.
A police source said there had been a number of incidents involving a Colac/Warrnambool man in his 20s evading police during the past couple of days.
The man has been driving a white Holden sedan with no number plates.
Colac police detectives have been searching for the offender.
Then on Wednesday morning a Port Fairy divisional van was rammed by the driver of the white Holden sedan.
That led to police searching for those who had been in the vehicle in Warrnambool soon after 11am in the Grafton Road, Moore Street and Cramer Street area.
The driver was arrested and two women passengers also taken into custody.
Police are still seeking another Colac man aged in his 20s.
During the ongoing search for missing male offender, two other men were arrested - one was walking down a footpath and is wanted on a warrant of apprehension while another man was riding a monkey bike along Moore Street.
They are now in custody and assisting police with their inquiries.
"They dumped the car at AquaZone and the two women and two men fled on foot," the police spokesman said.
Anyone with information is requested to contact the Warrnambool police station or Crime Stoppers on 1800 333 000.
