TEWKSBURY, Mass. -- A man who faces weapons charges says he was on a classified government mission. The Lowell Sun reports 59-year-old Francho Bradley of Frisco, Texas told investigators this when he and his girlfriend Adrianne Jennings, 40, were arrested at a Tewksbury, Massachusetts hotel Sunday.

The two are being held without bail after being arraigned Monday in Lowell District Court in connection with a large seizure of weapons at the Residence Inn Sunday.

Bradley called the police while away from the room to say he believed there was a break in because a video surveillance device that he had in the room had cut out, reports CBS Boston, and that he had a firearm in his hotel room unsecured. He also told police that he needed the weapons because he was on a secret mission for the government.

A search warrant was granted for the hotel room and the couple's vehicle where more weapons, ammunition and large capacity feeding devices were found including an AK-47, an AR-15 with a grenade launcher, a large capacity shotgun and a bump stock, according to CBS Boston.
