SAN DIEGO (CNS) - San Diego police searched Monday for a man and a woman alleged to have carjacked a motorist in the Encanto neighborhood.

A man told officers he was driving westbound in the 6300 block of Wunderlin Avenue just before 8 p.m. Sunday when he noticed a woman waiving at him, possibly in distress, said San Diego police Sgt. David Jennings. He stopped his vehicle, and she pulled out a hammer from her purse and demanded the car, he said.

Then, the woman's accomplice appeared with a knife, pulled the driver out of his car and punched him in the face, Jennings said, noting the woman also hit the victim in the arm with her hammer.

Both assailants fled in the victim's burgundy 1996 Nissan Sentra, California license plate No.6NFJ115.

Police described the male assailant as tall, thin and Hispanic. He appeared to be about 22 and wore a blue shirt with checkered blue and white shorts, Jennings said. The female assailant was described as Hispanic, about 21, about 5 feet 6, with a medium build. Jennings said she wore a brown shirt and blue jeans.

The victim declined medical treatment at the scene, Jennings said.
