WATCH: Video Shows Water Gushing From One Liberty Place In Center City

PHILADELPHIA (CBS/AP) - Water was seen gushing out from the side of a Philadelphia skyscraper over the weekend for an unknown reason. An onlooker took a video Sunday morning showing the water coming out of the top of One Liberty Place.

He says it continued for about five minutes before coming to an abrupt halt.

A security official at the 61-story, 945-foot- tall skyscraper referred calls to the management office, which was closed.

The fire department says this was a test of the fire protection systems.

Messages were left for the property manager and another official seeking comment.
