HONOLULU -- Federal authorities arrested a Japanese man Friday after he allegedly tried to board a flight to Tokyo with a stun gun in his carry-on bag.

Prosecutors charged Hiroki Suzuki with one count of carrying a dangerous concealed weapon while attempting to board All Nippon Airways Flight 1051.

An affidavit filed in U.S. District Court in Honolulu said Suzuki hid the Muscle Man stun gun in a small black canvas pouch in his carry-on bag.

A Transportation Security Administration official found the device during an X-ray scan.

Suzuki allegedly told FBI agents he bought the stun gun in Japan about a year ago for his personal protection.

U.S. Magistrate Judge Leslie Kobayashi released Suzuki on $25,000 bond so he can attend his grandfather's funeral in Japan. But Kobayashi ordered Suzuki to return for a hearing in two weeks.

Suzuki was represented by a federal public defender, who could not immediately be reached late Friday.

The affidavit alleged Suzuki, through a translator, acknowledged he knew the stun gun was in his luggage.
