A teenage cyclist's leg was badly injured in a hit and run in Christchurch.
Police are now calling for witnesses to the crash at the entrance to the Pak 'n Save supermarket on Wainoni Rd on Saturday, August 8.
Senior Constable Peter Carrington said an 18-year-old man was cycling south on the road between 9.15pm and 10.15pm when a black Toyota, possibly a Corolla, turned in to the supermarket car park in front of him.
The bicycle slammed into the side of the car and the cyclist fell off. The car's rear wheel then ran over the man's leg, causing significant injures.
"The driver did not stop and drove back out of the Pak 'n Save car park. It is not known in what direction the vehicle was headed when it left the car park."
Mr Carrington said a good Samaritan then took the cyclist to Christchurch Hospital's emergency department in her car.
"The victim has recently had surgery on his leg and is recovering at home," he said.
Police would like to speak to the good Samaritan as well as the two people -- a male driver and female passenger -- believed to be in the black car.
They, and any witnesses to the incident, are asked to call police on 03 363 7400.
