SAN FRANCISCO — The FBI has issued a nationwide alert to law enforcement agencies about a San Francisco man they consider armed and dangerous who is wanted for investigation of possessing explosives.
FBI spokesman Peter Lee said Sunday 42-year-old Ryan Kelly Chamberlain, II, was last seen in a dark blue, hooded sweatshirt and jeans.
Multiple agencies, including hazardous materials crews, searched Chamberlain’s apartment in San Francisco’s Russian Hill neighborhood on Saturday, blocking off the street to vehicle and pedestrian traffic for much of the day.
Lee gave no details Sunday about the nature of the investigation, but said authorities believe Chamberlain is acting alone.
“Right now we believe he is alone in the vehicle but we just don’t know, again, where his ties or his network is so we ask that any members of the public be on the lookout for anyone that matches this man’s description,” Lee said at a press conference outside FBI headquarters on Sunday.
Chamberlain is a white male, 6-foot-3-inches and 225 pounds with brown hair and blue eyes. He is traveling in a white 2008 Nissan Altima with Texas or California license plates, but authorities do not know where he is heading, Lee said.
The search warrant used to enter his home remains under seal.
On Saturday, hazmat crews were hosed down after leaving the two-story, gray 1970s-era building on Jackson Street. Some residents were also kept from entering their homes while the search was underway.
