Three foreigners -- a Briton, a Pakistani and a Taiwanese-American -- have been arrested in Cambodia for trying to smuggle 750 grammes of drugs out of the country, police said Sunday. Steven Bushel, Sha Hihan and Victor Chhan were arrested at midnight Friday in a hotel room where they were discovered with 450 grammes of crystal amphetamines known as "ice" and 300 grammes of a white powder used to produce the drug, anti-drug police investigator Chea Leng told Agencies. "We have monitored them for almost three months and we knew that they were trying to smuggle the drug out of Cambodia ," he said.
