HERCULES -- Police continue to search for a man who broke into a home after smashing through a back door Monday night.

Officers responded to a home on the 2300 block of Redwood Road at 8:20 p.m. for a call of a burglary in progress. A resident there said he had walked downstairs and found another man in the home, and he ran into a room on the second floor and locked the door before calling police. The suspect got into the home by shattering a back sliding glass door in a downstairs bedroom and forcing it open, the man told police.

Police said the resident did not see the man leave the home. Officers from San Pablo and Pinole as well a police dog unit helped officers search the area, but police were unable to find the suspect. No items were reported stolen from the home.

Less than a half hour later, police were called to a house on the 1800 block of Redwood Road, just blocks away from the home where the police had responded to the burglary call.

A resident told police they had found a handgun in their driveway that did not belong to them.

During a search of the area, police found that a bullet hole had pierced the home's garage door, leaving a dent in a vehicle parked inside the garage. Another resident reported hearing a gunshot and a vehicle speeding away from the area around 8:30 p.m., police said.

No injuries were reported.

The recovered gun left in the driveway was reported stolen out of Idaho in 2007.

It is unclear if the stolen gun was related to the attempted burglary down the road.
