WELLAND -- A police report penned by a Niagara Regional Police officer accused of leaking documents to the Hells Angels, and detailing criminal activity of associates of the outlaw biker gang, became the focus Tuesday in the ongoing retrial of Frank Dean Rudge.

Court heard from defence lawyer Ron Brady that the document was written by Rudge prior to his arrest and is crucial to the case because it proves his client's innocence.

Brady questioned why an officer, if he was associated with an outlaw motorcycle gang, would file a report on the group.

The document was found in Rudge's duty bag in his locker at the Port Colborne detachment at the time of the officer's arrest.

It was never introduced during Rudge's first trial, Welland Superior Court heard.

Crown attorney Robin Flumerfelt argued that the document is unimportant, and suggested all police officers write reports on criminal activities that may include the Hells Angels.

Former NRP Sgt. Thomas MacLean, Rudge's supervisor at the time of his arrest, was recalled to the stand by Brady and questioned about the police report found in Rudge's locker.

MacLean also dismissed it as having no relevance to Rudge's arrest.

Flumerfelt told Justice Peter Hambly he will rest his case Wednesday.

Rudge is being tried by judge alone.

Rudge has been suspended since his arrest and has been tried for charges of breach of trust by a public officer.

He was acquitted of those charges in 2010, but a second trial was ordered when the Ontario Court of Appeal overturned the decision in December 2011.
