US nabs explosives suspect after nationwide manhunt

US authorities have arrested a suspect who sparked a nationwide manhunt after explosives were allegedly found in his San Francisco home.

SAN FRANCISCO: US authorities have arrested a suspect who sparked a nationwide manhunt after explosives were allegedly found in his San Francisco home.

Ryan Kelly Chamberlain II, 42, was taken into custody by the FBI and the San Francisco Police Department, the FBI's bureau in the West Coast city tweeted late on Monday.

Just a day earlier, the Federal Bureau of Investigation had appealed to the public for help in tracking down the suspect, warning he "should be considered armed and dangerous."

He was last seen Sunday south of San Francisco.

The San Francisco Chronicle reported that Chamberlain was arrested within city limits and booked on suspicion of possessing explosives in violation of federal law.

The newspaper said Chamberlain, described as a political and media consultant, left what appeared to be an online suicide note.

"So much was broken from this past year-and-a-half, and from moments way back before that," it quoted the three-page letter, entitled "Goodbye," as saying. "I guess it was just insurmountable, and the time's up."

The San Francisco Chronicle also reported that a second note appeared on social media on Monday in which Chamberlain apparently stated that "Nothing they're reporting is true. No 'stashes.' Not 'armed and dangerous.' No car 'rigged to explode.'"
