The Red Cross has been called out to help residents affected by a downtown apartment fire.

The organization said over 100 people were evacuated from the Oak Tower apartment building Sunday afternoon.

Fire crews responded to the blaze at the high rise on 101 Avenue and 117 Street around 11 a.m.

“It went to a second alarm soon after the arriving crews,” deputy fire chief John Lamb explained adding they later made it to a three-alarm call.

Lamb said two of five people rescued were in serious condition including a young child believed to be about 5 or 6 years old.

“There is extensive damage on the eighth floor and some extension to the ninth floor.”

Emergency crews have been working to confirm that all residents have made it out of the building.

Officials from the Red Cross are on hand to offer emergency food, clothing and shelter.

Residents have been gathering in the gym at the Oliver School, which is at 10227 118 Street.

The cause of the blaze is still under investigation.

Lamb said there were about 60 fire fighters at the scene.
