Two men are in police custody after RCMP said they barricaded themselves inside a house with firearms and two women in Portage la Prairie early Tuesday morning.

RCMP said it all began around 11:30 p.m. Monday when they received a report of a suspicious man and a white car on the driveway of a house on Oak Bay. Officers arrived and found that a man inside the home had a firearm. Extra officers were then called in, including police dogs and negotiators.

RCMP said there were four people inside the home with an unknown number of firearms. Officers tried to enter the house, but barricades had been set up on the inside.

RCMP said they then used tear gas, at which point two women, aged 25 and 16, exited the house and were arrested. Two men remained in the house and barricaded themselves further. Officers were then able to forcibly enter the home and arrested the two men.

All four people were treated for minor injuries, and no officers were injured, RCMP said. The two men remain in custody while the two women have been released. RCMP is considering them witnesses and possible victims.

No names will be released as no charges have been laid yet. But police are familiar with one of the male suspects, who allegedly stole the white car from the same house on Oak Bay three days earlier. RCMP had been investigating the theft.

A car with a similar description was also at the scene of a gas station theft on the Trans-Canada Highway early Monday morning.

“The RCMP thanks the public for their cooperation in staying clear of the area while the events of this morning took place,” said Cst. Sean O’Keefe of the Portage la Prairie RCMP in a release.

“Public safety is our priority.”

The investigation continues.
