On Friday, Yongda Huang Harris was on his way from Japan to Boston when customs agents stopped him.
In his luggage, they found a smoke grenade, three leather-coated Billy clubs, a collapsible baton, a full-face respirator, various knives, a hatchet, body bags, a biohazard suit, handcuffs, leg irons and a device to repel dogs.
Harris was wearing a bulletproof vest and flame retardant pants. The 28-year-old lives in Boston, but has recently been working in Japan
The LAPD bomb squad determined that the smoke grenade fell under the United Nations’ explosives shipping classification, meaning it is prohibited on board passenger aircraft.
