(AP) Japanese authorities say they noticed nothing unusual about a man arrested in Los Angeles after getting off an airplane wearing a bullet-proof vest and packing body bags, handcuffs, knives and a smoke grenade in his checked-in baggage.
U.S. officials say the man boarded the flight at Kansai airport in western Japan and was arrested last Friday. He was charged with transporting hazardous materials.
An immigration officer at Kansai, Masahiro Nakamoto, says authorities reported nothing suspicious at the time the man is believed to have boarded. But Nakamoto says arriving passengers are checked more closely than those leaving the country.
A Transport Ministry official said as of Wednesday the U.S. has not requested assistance. He said more details were needed, but stood by the security measures at Japan's airports.
