A British journalist who sold 350 Ecstasy tablets to an undercover police officer was jailed for more than four years yesterday. Mark Seabrook, 38, was found guilty of two charges of trafficking in dangerous drugs and one of possessing cannabis. He had denied all the charges. Seabrook met Inspector Wong Kwong-hing and an informer at the Regal Airport Hotel on September 3, the District Court heard. He offered Inspector Wong 350 tablets for $140 each. He said there were samples under the sofa cushion on which he was sitting. Inspector Wong found three tablets in a plastic bag wrapped in tissue paper. Seabrook was arrested in the hotel's coffee shop later that day. While he was in Ho Man Tin police station, he ripped up a piece of paper. It was picked up by an officer and found to be a luggage receipt from the hotel, where police found Seabrook's bag. It contained 349 Ecstasy tablets hidden in a video cassette case. Officers also found 7.13 grams of cannabis in a sock in Seabrook's room at the Mariners' Club, Kowloon. Deputy Judge Stephen Chow said the amount of drugs involved was substantial and sentenced Seabrook to four years and four months in jail. He added seven days for possession of cannabis.
