Three assailants were being sought in connection with an attack in the parking lot of the Hayward BART station Sunday night in which a man was stabbed and a woman was beaten, officials said.

The attackers targeted the two victims, both 28, about 9:20 p.m. in the parking lot of the station at 699 B. St., said Alicia Trost, a BART spokeswoman.

The man was taken to a hospital, where he underwent surgery for stab wounds described by police as non-life-threatening. The woman was treated at a hospital for facial injuries and released.

A motive for the attack is under investigation. The condition and names of the victims were not immediately released.

The assailants all appeared to be 30 to 40 years old, police said, but no detailed descriptions were released.
