Ottawa training exercise explosion leaves 5 injured, 2 seriously

Two police officersand three paramedics were injured in anexplosion during an armed hostage-takingtraining exercise in Ottawa on Wednesday morning, police sources have toldCBC News.

The explosionoccurredjust after 10 a.m. ETduring a joint force-entry exercise into an abandoned residence, Ottawa police Chief CharlesBordeleau said. The training exercise involved Ottawa police officers, paramedics and RCMP officers.

The simulation involved other officers inside the house pretending to be victims and suspects, police sources told CBC News. The devices are "triple checked" before use andwhen a detonation occurs, all officers have to take cover before explosions, the sources said.

The two Ottawa police officers suffered minor injuries, paramedics said.

Two paramedics Supt. Craig MacInnesand Reid Purdy suffered serious injuries. Athird, Bradley Ross,suffered minor injuries, said Ottawa paramedic chief Anthony Di Monte at a news conference Wednesday afternoon.

MacInnes was one of the paramedics who subduedformer RCMP officer Kevin Gregson after he killedConst. Eric Czapnikin 2009.

The three paramedics are men in their30sand they all have previoustactical unit experience. They were wearing protective gear when the explosion occurred, Di Monte said.

Their injuries included second-degree burns onhands and legs. The MacInnes and Purdy were intubated as a precautionto prevent their airways from swelling shut, which can sometimes happen whenhot gas is inhaled, Di Monte said.

The paramedics donot appear to have sustained any respiratory damage.

Di Monte said Ross, meanwhile, rushed to help his more seriously hurt colleagues after the blast. The paramedics were first taken to the Queensway Carleton Hospital, and were later transferred to the Ottawa Hospital's General campus.

Training operation specifics unclear

Earlier Wednesday, Bordeleausaid police can't go into specifics about the training operation because of the investigations under way.

"Explosives are used in training exercises and real-life operations to assist officers to forcibly enter intoresidences or businesses to assist them into getting access into those buildings," he said.

"What type of explosives, how it was detonated I can't comment on that because that will be part of theSpecial Investigations Unit investigation."

Ontario's Ministry of Labour is also investigating.

TheSIUinvestigates incidents in which police officers are involved in serious injuries or death.Bordeleausaid the SIU invoked its mandate becauseparamedics are considered civilians.

"Paramedics are part of the training exercise because they work hand-in-hand with the Ottawa police service to ensure the safety and security of all during these types of operations," Bordeleau said.

Witnesses near the training facility on March Road in Kanata told CBC News they heard a "big bang" that sounded like an explosion.
