YAKIMA, Wash. (AP) — A 20-year-old member of the military was arrested after trying to get through airport security with two training grenades in a carry-on bag, police said.

Transportation Security Administration agents spotted the grenades using a belt scanner at Yakima Air Terminal around 11:15 a.m. Sunday, Police Sgt. Tim Bardwell said.

The grenades contained live fuses but had no explosives packed around them, Bardwell told the Yakima Herald-Republic. The man was released Sunday afternoon while prosecutors and the FBI look into the incident.
