A Three Towns police sergeant has walked free from court after rape charges against him were dropped. 

35-year-old Blair Pettigrew, from Ardrossan, was due to stand trial at Edinburgh High Court charged with rape and sexual assault but the case collapsed last week. 

Sergeant Pettigrew, a dad-of-two, now faces an internal enquiry by Police Scotland, with a national newspaper claiming that one of the alleged victims was coerced by other police officers into making false allegations. 

The former Volunteer of the Year was yesterday re-instated as President of North Ayrshire Athletics Club. 

Sgt Pettigrew had always denied the allegations - which spanned from 2005 until 2015.

A spokesperson for the Crown Office said: "It is the duty of the Crown to keep cases under review and after full and careful consideration of the facts and circumstances, including the admissible evidence currently available, Crown Counsel instructed there should be no further proceedings at this time.

"Should the evidential position change, the Crown reserve the right to re raise proceedings.

"The complainers in the case have been advised of the decision."

A spokesperson for Police Scotland said: "We acknowledge the decision by COPFS. Any reports of crimes committed by police officers or staff are investigated thoroughly. As soon as the circumstances in this case were reported an investigation was conducted  and a report was submitted to the Procurator Fiscal.

"Police Scotland is absolutely committed to thoroughly investigating reports of sexual crime and providing the necessary support and advice to victims, irrespective of ‎who the person suspected is or when the incident took place."

They added: "A report will be submitted to the Assistant Chief Constable, Professionalism and Assurance for his consideration."

The Herald contacted Blair Pettigrew for comment but he refused as he is still employed by Police Scotland.
