A woman was sexually assaulted in a car after being offered a ride to a bus stop last week.
Canterbury police said the assault took place in a vehicle parked in an enclosed yard off Dickeys Rd in Belfast, Christchurch, about 2.15pm on April 7.
The 22-year-old woman was sitting outside Mico Wakefields by the bus stop on Cranford St shortly after 2pm, and was "visibly upset", detective Wayne Boyd said.
A passing motorist stopped to check she was OK, and offered her a lift to the bus stop on Main North Rd.
"In her heightened emotional state the victim accepted the man's offer as she thought it was only a short distance to the bus stop on Main North Rd," Mr Boyd said.
"The offender is reported to have driven the victim to the motorway end of Main North Rd where he turned into Dickeys Rd and parked in an enclosed logging yard approximately 300 metres from the intersection."
The woman was sexually assaulted in the car for some time, before she was dropped off at Main North Rd near Johns Rd.
She is being supported by Canterbury police and Victim Support.
The offender is described as Maori, aged between 30 and 40, clean shaven and wearing a white t-shirt and 'Dickey' brand shorts that came to below the knee.
He was driving a dirty white early model Mazda Familia four-door sedan with tinted rear lights. It was clean and tidy inside.
Police want to hear from anyone with information about the man or vehicle described, or any other information on the inquiry.
