Arson likely at Kelowna, B.C., hotel

Kelowna RCMP are investigating after a suspicious fire burned three floors of the Coast Capri hotel.

Officials say the fire started at about 1:30 a.m. PT Saturday on the hotel's sixth and seventh floor stairwells, spreading to the seventh floor and eighth floor mezzanine.

Deputy fire Chief Thomas Doherty said heavy smoke filled the top floors of the hotel, and filled the hallways from the third to seventh floors.

"Investigators have confirmed that there were to separate points of origin for this fire. One fire was on the sixth floor exit stairwell landing and the other was in a seventh floor storage room which extended up into the eighth level," said Doherty in a statement.

All of the hotel's 358 guests were forced from their rooms.

Doherty said some were allowed back inside to parts of the hotel not affected by smoke and fire, while others were sent to nearby hotels for the night.
