A stabbing Friday in City Heights that investigators initially believed occurred during a robbery turned out to be a case of self-inflicted injury.

Officers responding to an apparent assault at 38th and Wightman streets shortly after 11:30 a.m. found a man in the area suffering from stab wounds. Medics took him to Scripps Mercy Hospital for treatment of injuries of undisclosed severity.

Preliminary reports indicated that the man had been assaulted by two suspects during a robbery. Detectives, though, determined that he had inflicted the wounds on himself, possibly due to a mental-health crisis.

“There was no crime,” San Diego police Sgt. Michael Tansey said.

It was not immediately clear why police at first thought a robbery had occurred.
