A police officer who believes in black magic has been arrested on suspicion of smuggling dead human fetuses, said to be from Thailand, into the city. The 28-year-old officer was arrested in Hung Hom at about 4pm yesterday for allegedly bringing in the whole or partial fetuses to sell, a police spokesman said. He was detained last night for questioning and has not been charged. The Kowloon West Regional Crime Unit is investigating. The arrest came a day after a report in a Chinese-language newspaper exposing the activities of the officer, from the Kowloon West Emergency Unit. The reporter had posed as a buyer. The officer, identified as Barry Ma, told the reporter he had obtained the whole or partial dead human fetuses from Thailand. He then sold them online, posting photos of the fetuses, with captions, or took them to the mainland to sell. He also gave instructions to buyers as to how they could dodge X-ray inspections when taking the fetuses through customs - and how to escape if they got caught. The report said Ma had openly sold the fetuses on several websites. And he could be easily identified in full police uniform on his Facebook page. Ma told the reporter he had believed for five years in the magical power of the dead human fetuses. He also bragged about his sideline in trafficking the fetuses, and his exploits with women. He asked the reporter for HK$138,000 for one of the fetuses - and showed him one that he was carrying with him. The report said Ma had been approached by buyers from Hong Kong, the mainland, Macau and Taiwan. Black magic rituals are common in parts of Southeast Asia, especially in Thailand. Those who believe in black magic use the dead human fetuses and other items in a bid to help improve their fortunes. In May last year, a 28-year-old British citizen born in Hong Kong to Taiwanese parents was arrested in Bangkok with six dead human fetuses aged two to seven months that he was apparently trying to sell. The origin of the fetuses has not been confirmed but it is believed the man was trying to smuggle them into Taiwan.
