A POLICE force is facing its third serious investigation for officer wrong doing in less than a month after a man was seriously injured.

North Yorkshire Police faces questions by the Independent Police Complaints Commission (IPCC) over an incident.

Officers were called four times about a man walking along the A64 on April 11 near to York and responded each time.

The force’s officers failed to find the man on two of the occasions they were called and he was later struck by a car and injured and the IPCC called in.

Steve Read, the force’s head of professional standards, said: "We voluntarily referred this incident to the IPCC.

"We shall be working with the IPCC investigation to establish whether any lessons can be learned from our response to the incident. "We have an open and transparent policy with regard to incidents of this nature and welcome any learning points which may help to improve our service."

Grahame Maxwell, the force’s chief constable and his deputy Adam Briggs are already under IPCC investigation.

It is claimed they used their position to help family members avoid part of the selection process to become police officers.

Two civilian staff are also under IPCC scrutiny in the same case over trying to scam the selection procedure too.

Mr Briggs also faces a separate allegation under IPCC study that he used police equipment to watch a computer disc with inappropriate material on it.

The latest incident began with a 999 call from a driver to inform officers of a man walking along the A64 that he had nearly run over.

Police officers attended the scene and spoke to the man at 5.30pm on Saturday, April 11, near to Grimston Bar, York.

Two further calls were made at approximately 6.25pm and 6.55pm about the same man on the A64 and the police responded but failed to find him.

A fourth call was made to the police at 10.55pm about a man walking by the A64 in the same area but he was run over before they got there.

A 36-year-old man sustained serious injuries and he is being treated in hospital.

Nicholas Long, IPCC commissioner, said: "We will want to determine whether anything could or should have been done differently.

"The investigation will examine the appropriateness of the police response to the telephone calls from concerned members of the public."

North Yorkshire Police Authority said it had no comment on the matter which was between the force and the IPCC.
