REGINA -- A Saskatchewan RCMP officer has been charged with impaired driving and the way that three other Mounties' handled the case is being reviewed.

The RCMP say an off-duty member in Fort Qu'Appelle, east of Regina, got a call at his home Dec. 15 from a waitress at a local establishment who said there was a man she felt should not be driving.

The man in the establishment is a constable in the Fort Qu'Appelle detachment who was off-duty at the time.

A criminal investigation was then launched that led to Alphonse Noey being charged May 30 with one count of operating a motor vehicle while his ability to operate the vehicle was impaired by alcohol.

Supt. Dave Fenson defended the time frame of the investigation.

"Some investigations take longer than others to conduct and to complete, depending on what followup is required," Fenson said Wednesday.

Fenson could not say why the waitress called the first officer at home.

He says the RCMP prefers the public call the local detachment or 911, but he acknowledges sometimes that doesn't happen.

"Speaking in general, I can say that it is not uncommon for some of our employees to be well known in smaller communities, including where they live and to be contacted. This means from time to time, that these members will receive calls at their residences," he said.

Noey, who has been with the RCMP for 13 years, has been on paid administrative leave since May 5. He is scheduled to make a court appearance June 12.

The RCMP also say the actions of three other officers, including the off-duty member who got the call at his home, will be reviewed to make sure all the rules were followed.

"Due to the nature of the incident and the fact that it involved a member of the RCMP, we've taken steps to review the response that took place that day and who responded to initial complaint and what was done," said Fenson.

"In conducting such a review, we want to take a more in-depth look at the response and the conduct which took place. Furthermore, we want to ensure that the response and the conduct met with our expectations, the RCMP's expectations and the public's expectations. We want to be fully satisfied that everything that could be done was done."

Fenson could not say how long the review would take.
