Some of the evidence presented in the Shane Cribb case in the Alexandra District Court in 2006 is being investigated by Police National Headquarters.
Mr Cribb was convicted of careless driving causing injury after his vehicle collided with a four-wheel-drive vehicle being driven by Senior Constable Neil Ford on Earnscleugh Rd at Alexandra in 2005.
His conviction was dismissed last month after a re-hearing was granted, and police did not present any evidence.
Inspector Andrew Burns, of Dunedin, has confirmed a decision to investigate discrepancies in the position of the four-wheel-drive had been made immediately after police decided not to offer any further evidence at the re-hearing.
Insp Burns said police had received new information that the position of the vehicle was in a different place than was reported at the time of the crash, based on the contents of the statement that was made at the time.
"Quite clearly the information we had at the start was why the charge was laid. New information from other witnesses has changed that, and if we had had that information at the time we would not have charged Mr Cribb," he said.
The Otago Daily Times has not yet been able to confirm the terms of reference for the investigation. Snr Const Ford could not be contacted yesterday.
