She said the man hadn’t managed to close the door of their car before they swerved into the truck lane to the left and sped off as fast as they could causing the man to fall out onto the road.
“He couldn’t get the door shut and couldn’t get his legs in at that speed so just fell out,” she said. “We didn’t know what to do so we just kept driving.
“The other two men just ran off on their own over the train tracks.”
Police say the men went on to steal another member of the public’s vehicle after escaping about 2.40 pm when the transport van was heading north towards the Mt Eden Corrections Facility - and a manhunt remains underway.
“Police have since been notified and our staff are making inquiries to locate these individuals, including support from the Police Air Support Unit, Eagle,” Police Tāmaki Makaurau director of deployment Shanan Gray said.
A Corrections spokesperson said police were informed immediately and are actively searching for them.
“We encourage anyone with information about the prisoners’ location to contact Police on 111.
“Public safety is our top priority. Any escape is unacceptable and an immediate review into how this incident occurred will be carried out.”
