Five current and former RCMP officers will be in a Winnipeg court on Monday accused of offences ranging from fabricating evidence to torture.

The charges arise from a private prosecution launched by a Portage la Prairie man.

Matthew Gray, 47, filed complaints against up to 15 RCMP officers in civil and criminal court after he was handcuffed and jolted multiple times with a Taser stun gun in June 2003.

Last month, a provincial court judge agreed there's enough evidence to continue with charges against five of the officers.

Gray said he was relieved someone is finally taking him seriously.

"I always thought I was a man of integrity and a man of my word and when I spoke, people always knew by my history that things were true. But once I said this, I only got scorn, ridicule and contempt," he said in an interview with CBC News.

The RCMP would not comment on the case because it's before the courts.

The province has appointed a special prosecutor, Marty Minuk, to review and monitor it. Minuk can intervene at any time and could drop the charges if he doesn't think there is a reasonable chance of conviction. He also could prosecute it like any other criminal case.

Suffers from mental disorders

Gray, a retired soldier, has said he suffers from post-traumatic stress, bipolar and anxiety-panic disorders. In June 2003, he wanted to be admitted to a mental health facility, so he called a hospital psychiatric ward for help.

According to court documents filed in 2005, the hospital called RCMP, fearing Gray might be a danger to himself.

There was some confusion over whether Gray's committal to hospital would be voluntary or involuntary, and RCMP said he became violent and aggressive and a scuffle ensued.

RCMP documents indicate Gray was handcuffed at his own request and a Taser was used on him twice in the hospital.

After he was given sedatives, the Taser was used again — more than once — during an ambulance ride to another hospital in Winnipeg, according to RCMP documents. An RCMP weapon-use report filed in court said Gray became "extremely aggressive" in the ambulance and freed himself from some restraints.

Police cite fears for safety

Officers used the Taser in the ambulance out of fear for the safety of ambulance attendants, police officers, other drivers on the road and Gray himself, the RCMP previously stated.

There is dispute over how many times the Taser was used on Gray. He alleges it was used as many as eight times, RCMP say four times, and hospital records indicate six.

Gray said police assertions that they arrested him under the Mental Health Act are false. Consequently, he believes police had no jurisdiction to detain him or use force against him.

"I told the RCMP I smelled like roast beef because the burns were so long," Gray told CBC News.

He took his concerns to the RCMP Complaints Commission but it ruled the police did not apply excessive force. So Gray started a civil lawsuit and brought private prosecution charges against the officers in criminal court.

"I want to see justice all the way through," he said in an interview. "I want to see these officers explain why they did what they did."
