FREMONT -- Police are searching for a violent home invasion robber who doused a woman in the face with pepper spray when she opened her front door, struggled with a man in the home, and then escaped Thursday night, police said.

Police recovered an assault rifle in the home in the 4800 block of Porter Street but police said the man could still be armed with another gun and is considered dangerous.

"We still do not yet have a motive in this crime,'' said Fremont police spokeswoman Officer Geneva Bosques. "It appears he had a plan in place, but we aren't able to determine at this point if this was random."

Newark and Fremont police along with the Fremont SWAT team are doing yard checks on Porter Street, and the road is closed. Residents on that street are being asked to remain inside until police complete their search. A California Highway Patrol helicopter is helping with the search from the air.

Shortly before 6 p.m. Thursday, police said the man rang the door bell, used the pepper spray on the woman and then fought with a man at the home, firing shots during the struggle. The man, woman and two children got out of the home and the adults were treated for minor injuries. The children were not injured.

The suspect is described as a Hispanic man, roughly 30 years old with a long, bushy ponytail, goatee and a skinny build with tattoos above both eyebrows. He was last seen wearing a black zip-up gray jacket, a gray T-shirt and blue pants.
