JERSEY CITY (CBSNewYork) — Officials and residents alike were puzzled Friday when an object mysteriously blasted a hole in a house in Jersey City.

Chopper 2 was over the scene after it happened at a home on Western Avenue in the Heights section.

The object bore a hole straight through the wall over the home’s doorway.

Firefighters say it was caused by a six-foot long cylinder of compressed gas or air that flew like a missile and crashed into a home.

They think it may have come from a nearby scrap metal yard.

Thankfully, nobody was hurt.
