A man is behind bars this morning, after he allegedly stabbed a veteran San Francisco police officer during an altercation at SFO.

SFO spokesperson Doug Yakel, who spoke with Bay City News, says that at around 2:30 p.m. Tuesday, a "suspicious person" was reported "walking near a lower level roadway" at the airport's Terminal 1.

Officers who responded to the report tracked the suspect to the terminal's baggage claim area.

"When the officer asked the man if everything was okay the man began swinging at the officer with a double-edged knife," ABC 7 reports.

Speaking with ABC 7, Deputy SFPD Chief Denise Schmitt says "In this case it happened so quickly the officer reacted with the weapons that he had in his hands and those were his hands."

In the scrum, Schmitt says, "The officer, unfortunately, suffered a stab wound to his left leg, another stab wound to his hand and some other cuts."

SFPD spokesperson Officer Robert Rueca says that the injured officer is a 49-year-old male who "was treated and released from the hospital for lacerations to his hands, neck, face and leg." ABC 7 reports that the victim "has 23 years of experience and has worked at the Ingleside, Bayview and Tenderloin stations. He started working at the airport in September of 2003."

"The first thing he said to me at the scene when I asked him how he was doing was, 'Well I've had better days,'" Schmitt told ABC 7.

Schmitt says that the FBI was notified of the incident, and emphasizes that there was no connection to terrorism suspected in the matter.

The suspect, identified by Rueca as 64-year-old Dooris Johnston, was taken into custody at the scene. He had injuries to his hands for which he was medically evaluated, ABC 7 reports, then was "was booked into the San Mateo County Jail on charges of attempted murder of a peace officer and threats to commit violence," Rueca says.

Rueca says that Johnston's last known address was in San Francisco. According to NBC Bay Area, Johnston is expected to appear in court today at 1:30 p.m.
