There's a manhunt for a missing FBI agent in California, where authorities are worried he may be armed.

FOX News Radio's Chris Foster reports:

FBI Agent Stephen Ivens, believed to be armed and possibly suicidal in the mountains east of Burbank, California, where he lives with his wife and one-year-old.  He went off on foot, missing since Friday night.  

Police searched his home and did not find his handgun, but they say they do not believe he is a threat to the public.

Ivens, an FBI agent for three years now, a Los Angeles police officer before that.
