A woman was arrested on suspicion of assault with a deadly weapon after an incident in the Mission in which a man was slashed in the face with a knife, police said.

The 19-year-old victim and the 56-year-old suspect were at 16th and Mission streets about 3:27 p.m. when the victim told the suspect her radio was too loud, police said.

The suspect reportedly grabbed the victim’s beer and smashed it against a wall, police said. The victim responded by grabbing the suspect's radio and smashing it against the wall.

The woman is then alleged to have pulled out a knife and slashed the victim’s face, police said. She was later arrested.

The man's injuries were not life-threatening.
