TOKYO (Kyodo) -- Customs authorities at Tokyo's Haneda airport have seized 15 kilograms of cocaine from a single airline passenger, a record for Japan, they said Wednesday.

Customs officers found the cocaine, with an estimated street value of 372 million yen ($2.4 million), concealed in 15 candy boxes inside a suitcase in the possession of a 25-year-old Canadian man.

The man, who said he works in the construction industry, arrived at Haneda airport from Toronto on Dec. 21 at around 10:30 p.m. The cocaine was discovered during a routine customs inspection, and he was arrested early the following morning.

The Haneda branch of Tokyo Customs filed a criminal complaint with prosecutors on Jan. 8, and the prosecutors have since indicted him.
