Fire crews were dispatched to a Burnaby apartment building after a massive blaze broke out late Tuesday afternoon.

Authorities said the fire was reported around 5 p.m. at the Cascade Village complex near Linwood Street and smith Avenue.

The cause hasn’t been confirmed, but neighbours said it might have sparked in a suite that was under construction on one of the upper floors.

Flames quickly spread to the roof, part of which collapsed after becoming fully engulfed.

No injuries have been reported.
