A man dressed in a bulletproof vest and fire-resistant pants has been arrested at Los Angeles International Airport after a smoke grenade, gas mask, leg irons and weapons were discovered in his luggage, federal authorities say.
Boston-bound Yongda Huang Harris, 28, was arrested on Friday on suspicion of transporting hazardous materials on a flight from Japan, US Immigration and Customs Enforcement officials said.
Harris was not co-operating with federal officials attempting to interview him, according to a US official.
The official said Harris was not believed to be linked to a terrorist organisation but his motive had not been determined.
“Harris drew suspicion when US Customs and Border Protection officers at the airport noticed he was wearing the bulletproof vest and fire-resistant pants under his trenchcoat.
That triggered a formal investigation by Homeland Security special agents.
In a search of Harris’s checked luggage, numerous suspicious items were uncovered, including knives, body bags, a hatchet, a collapsible baton, a biohazard suit, a full-face respirator, billy clubs, a respirator, handcuffs, leg irons and a device to repel dogs, authorities said.”
