FREMONT -- Authorities said they are looking for a pair of men who escaped two police perimeters Thursday after they broke into a home in the Mission San Jose neighborhood.

No injuries were reported.

A woman called police at 9:52 a.m., saying that two men were trying to break into her home in the 43600 block of Excelso Drive near Mission San Jose Park, said Detective Bill Veteran.

While on the phone, the resident locked herself in a bedroom as the suspects forced their way into her residence, Veteran said.

Officers set up a perimeter in the area, then entered the house to prevent the suspects from reaching the woman, police said.

The suspects ran outside and into the residential neighborhood, but escaped the perimeter despite the presence of a police dog and a California Highway Patrol helicopter, authorities said.

A few hours later, the men returned to their vehicle still parked near the home and drove away, Veteran said.

Officers followed the suspects, who abandoned the vehicle in the intersection of Decoto and Perry roads in Union City, and then fled on foot, police said. Officers set up another perimenter, but the suspects again avoided capture, Veteran said.

No arrests have been made.

Police described the first suspect as a black man, 20-25, 6-foot, thin build, and wearing black pants and a teal short-sleeve shirt. The second suspect was described as a black man, 18-20, 5-foot-10, thin build, and
