FREMONT -- A man was stabbed in the head and arm and sprayed in the face with an unknown substance during an armed robbery outside a city motel over the weekend, police said.

Officers were dispatched at 7:30 p.m. to Washington Hospital at 2000 Mowry Ave. for a report of an assault with a deadly weapon, said police spokeswoman Geneva Bosques.

When police arrived at the hospital they spoke with a 30-year-old man who told them he was at the Good Nite Inn at 4135 Cushing Parkway and was planning to walk across the street to a gas station when two suspects, a man and a woman, approached him.

The female suspect sprayed the victim in the face with an unknown substance, police said, and the male suspect cut the victim's arm with a five- to six-inch bladed knife and then stabbed the man in the left temple.

The male suspect then pinned the victim down and the female suspect reached into the victim's pocket and stole his cell phone. The two suspects then ran off, Bosques said.

The man suffered minor to moderate injuries and was treated and released from Washington Hospital, Bosques said.

Police described the male suspect as a Hispanic man, in his 20s, 6 feet tall and 180 pounds. He wore a gray beanie, a light gray T-shirt and blue jeans.

The female suspect was described as a white woman in her 20s, 5 feet 5 inches tall and 125 pounds. She wore a white top and blue jeans.
