LOS ANGELES (AP) — A U.S. official says a man arrested at Los Angeles International Airport wearing a bulletproof vest and flame-retardant pants is not cooperating with federal investigators attempting to interview him.
Yongda Huang Harris was arrested Friday on suspicion of transporting hazardous materials after authorities say they found a smoke grenade, gas mask, leg irons and weapons in his luggage.
The U.S. official said Tuesday that investigators do not believe that the 28-year-old is linked to terrorist organizations, but they have not yet determined a motive.
The official spoke on condition of anonymity to discuss an open investigation.
