San Francisco police are investigating a kidnapping after a man was held for several hours by three suspects, who beat him with brass knuckles while one of them broke into his house and stole a handgun, authorities said Monday.

Around 11 p.m. Thursday, police responded to a report of a man who had checked himself into a hospital and told staff there that he had been beaten and kidnapped, said Officer Grace Gatpandan, a police spokeswoman.

The victim, identified only as a 23-year-old man, told investigators that he had been on the sidewalk near the corner of Orizaba and Holloway avenues in the Ingleside neighborhood when he was approached by three men between the ages of 20 and 30, Gatpandan said.

The attackers hit the victim repeatedly in the head and face with brass knuckles and took him to an unknown location. Two of the three assailants held him there for several hours while the other man broke into his house, making off with a handgun, Gatpandan said.

The victim was released by his captors and drove himself to a nearby hospital, Gatpandan said. It was unclear whether the victim was specifically targeted or if the attack was random.

Police urged anyone with information about the incident to contact investigators at (415) 575-4444.
