A man was arrested for robbing a woman of her beef teriyaki sandwich in San Francisco's Ingleside neighborhood on Thursday afternoon, according to police.



The 61-year-old victim set her sandwich down on a table at an establishment in the 1200 block of Ocean Avenue and then went to get a drink.



When she returned, a 23-year-old man was at the table eating her sandwich, police said.



The woman confronted the man, who punched her in the face and fled. Police arrested him a short time later.



The woman was taken to a hospital with pain to her face, but her injuries were not severe.
