PITTSBURG, Calif. (KRON) — A vacant restaurant in Pittsburg is damaged after a two-alarm fire Tuesday afternoon, the Contra Costa County Fire Protection District announced on Twitter. The fire broke out on the 2900 block of Harbor Street where the property was “extensively” damaged.

The fire is currently out, and there were no injuries reported. Officials said the fire began in a storeroom inside the restaurant — possibly due to a cooking fire.

There were homeless people inside the restaurant ahead of the fire, officials said. That vacant restaurant has seen “considerable” homeless activity, including in another fire during the weekend.
