Three vehicles were involved in a crash last night at the intersection of Andersons Bay Rd and the Southern Motorway.
Acting Senior Sergeant Ben Butterfield, of the Southern District Command Centre, said one person was taken to hospital with minor injuries after the 8.45pm crash.
Another was at the police station undergoing breath-testing last night.
''Alcohol is suspected as the cause of the crash,'' Snr Sgt Butterfield said.
