BREMERTON, Wash -- The FBI and U.S. Navy are investigating a break in at the Naval Base Kitsap-Bangor that occurred Monday morning.

A group of five activists - ranging in age from 60 to 83 - say they cut through two security fences near a weapons facility around 6:30 a.m. They were about to cut another fence when they were arrested.

Navy officials say the five were cited for trespassing and released Monday afternoon. They added at no time was the safety of Navy personnel, property, or the public threatened in any way.

After their arrest, the group said in a statement to the media they were protesting "illegality and immorality of the existence of the Trident weapons system."
