A 35-year-old man is in custody after barricading himself and a woman in a Colony Street apartment for hours Monday night.

Police were called to the apartment at about 3:30 p.m. and blocked off the street between Broadway and York Avenue. They remained on scene until about 12:45 a.m. Tuesday, a police spokesperson said.

Dozens of officers with guns drawn, including the tactical support team and the Winnipeg Police Service armoured vehicle, were involved in what police described as a "serious incident."

Police spokesperson Const. Tammy Skrabek told reporters on Tuesday the man had barricaded himself in the apartment with a 28-year-old woman, telling police he had a firearm.

Police were initially called to the apartment by another woman, 26, who told police the man had beaten her unconsciousness, causing her to flee with her young child after she awoke.

The situation was treated as an armed and barricaded incident, which is essentially a stand-off, Skrabek said.

Tactical support team members and additional general patrol officers secured the area.

At around 12:30 a.m., police were able to enter the barricaded suite and safely removed him and the woman he had been holding against her will. She was not not physically injured, though she told police she had been assaulted by the suspect on Jan. 4 as well.

The woman who fled the apartment and reported the assault was treated for minor injuries.

The man is now facing a litany of charges, including assault with a weapon, forcible confinement and theft under $5,000.

People weren't being allowed to come and go from the apartment in question, or the two buildings on either side during the incident, police said.

Some tenants had been escorted out earlier in the day for their own safety, police said.
