Roof collapse on Queens warehouse

There was a partial roof collapse at a Queens warehouse on Monday night.

It happened at a Best Buy storage union on 49th St. in Woodside.

No one was hurt but officials say it doesn't appear that winds were a factor.

Fire officials say the roof cave-in kicked out a wall on one side of the building.

ConEd also responded after firefighters say the collapse knocked out a gas line.  The buildings department was involved in the investigation.
