(NECN) - A Boston man arrested at Los Angeles International Airport on Friday is set to make his first federal court appearance Tuesday afternoon on a charge of transporting hazardous materials in his checked luggage.
The suspect, 28-year-old Yongda Huang Harris, allegedly had a smoke grenade, a hatchet, knives, a gas mask, biohazard suits and body bags in his checked luggage.
Harris had arrived at LAX from Japan.
Authorities say TSA agents became concerned because Harris was wearing a bulletproof vest and flame retardant pants beneath his trench coat.
