B.C.'s independent investigations officer (IIO) has deployed investigators to Kamloops because the suspect in the Wednesday morning shooting of an RCMP officer sustained a gunshot wound to his arm.

The IIO initially sent out a tweet with the information Wednesday night. It says the suspect was injured during the initial shooting incident.

The IIO says it is still trying to determine if the injury is serious enough to warrant their continued involvement. 

RCMP reported that at the time of the shooting, a police officer backing up Cpl. Jean Rene Michaud's returned fire after Michaud was shot,

Kamloops RCMP announced Wednesday afternoon it had arrested a 36-year-old man.

The IIO is responsible for looking into incidents involving police and that result in death or serious harm.

At a news conference Wednesday afternoon, Supt. Brad Mueller said the arrest of a single suspect was made "without incident" by the RCMP's emergency response team in the Batchelor Heights area of Kamloops around 3:30 p.m. PT.

Michaud shot during traffic stop

Michaud, a 13-year veteran of the force, was shot and critically wounded during a traffic stop. He is 40 years old and has a wife and two young children.

"The events are a sobering reminder of the dangers that police officers face every day while they are serving and protecting their respective communities, and I can't tell you the impact that an incident [like this] has on our policing community," Mueller said.​

A massive police manhunt using roadblocks, helicopters and police dogs took place in the neighbourhood after the shooting.

Mueller said the wounded officer has been in surgery and is in critical but stable condition at Royal Inland Hospital with his family at his side.

The incident began when the uniformed officer, who was driving a marked cruiser, stopped a vehicle around 2:45 a.m. at Batchelor Drive and North River Drive.

Mueller said Michaud was wearing a bullet-proof vest and driving a marked police cruiser as he approached a vehicle as part of an ongoing investigation.

"I can say that our officer was fired upon as he approached the suspect vehicle and the backup officer who was also in attendance returned fire towards that vehicle," he said.

Awoken by gunfire

Dennis Maruschy, who lives a block and a half from the shooting scene, said he was awakened by the sound of gunfire.

"It sounded like one guy emptying a clip — pop, pop, pop, pop," Maruschy said. "It sounded like someone emptying a clip in a semi-automatic."

Kamloops Mayor Peter Milobar said he was shocked to hear the news.

"I guess you always hope that you live in a community where something like this wouldn't happen," he said.

"I think that the RCMP are all very well aware of the risk they are assuming and the fact that they're still willing to put themselves out there for us on a day-in and day-out basis is beyond commendable."

Mueller said there are a lot of solemn faces at the RCMP detachment.

"People who don't wear the uniform and don't put their lives in danger every day don't have a true understanding of what you go through in those types of situations," he said.
