A man in a wheelchair detonated a pipe bomb inside an east Oakland health clinic Tuesday night, according to authorities, who believe his intent was to commit suicide.

Oakland police said the explosion occurred at 6:26 p.m. inside the San Antonio Neighborhood Health Clinic, 1030 International Blvd.

Oakland police Lt. Rachael Van Sloten said the man, whose name has not been released, entered the clinic lobby and detonated the bomb, killing himself. No one else was injured, she said. Investigators concluded the incident was isolated and labeled it a suicide.

“At this time it doesn’t appear to be related to terrorism,” she said.

The Alameda County Sheriff’s Department sent its bomb squad to assist with the investigation and make sure no other explosive devices were inside the clinic.
