MINNEAPOLIS (AP) — Minneapolis police are looking for the man who punched a woman in the face during a road rage incident.

The victim, a social worker, says she was on her way to see a client when she encountered a driver who seemed to be in a hurry. She says the driver was switching lanes and tailing other drivers. The woman made a turn and heard screeching brakes and when she got to a stop sign Wednesday the angry driver had blocked off her minivan.

Witness Dylan Bauer tells WCCO-TV he heard yelling and swearing. He says the man opened the minivan and punched the woman twice in the face, then sped away. Bauer and other drivers came to the woman's aid. She suffered bruising and swelling to her face.

Police are investigating.
