A man was stabbed Sunday in the Bay Park neighborhood.
A witness was driving on the 4100 block of Clairemont Drive shortly after midnight and saw the victim, a 23-year-old male, who had been stabbed in the arm, said Officer Robert Heims of the San Diego Police Department.
The victim did not tell police what happened, but a witness said she saw a man or boy stab the man and then walk away, Heims said.
The suspect is described as Hispanic, 5-foot-7 inch man with short hair, wearing a black sweatshirt, jeans and a beanie-type hat.
Heims said the victim was treated for non-life-threatening injuries.
