Canto-pop singer Jill Vidal has been charged over suspected heroin found in her luggage or hotel room and will face a Tokyo court on April 24. Vidal's record label Amusic confirmed that the troubled star would appear in court and the singer's manager Joe Chan and father Joey would travel to Japan for the trial. But it was not known if her twin sister, Janice, who is also a popular singer, would attend the trial. A court official in Japan said Vidal would appear in Tokyo District Court in Kasumigaseki, Chiyoda, at 2.30pm on April 24. Shahmim Khattak, a Hong Kong barrister who is familiar with Japanese law, said Vidal - who is better known in Hong Kong by her stage name, Wei Si - faced charges under the Narcotics and Psychotropic Control Law and might be forced to receive treatment for drug addiction in a hospital detention centre. 'This law targets offences involving hard drugs like heroin, not cannabis,' he said. Earlier this week it was reported that several packages suspected of containing heroin were found in her luggage or in her Tokyo hotel room. A Hong Kong government source revealed that the Japanese authorities had reported that Vidal would be prosecuted for possession of a dangerous drug. It was reported that the amount of the alleged drug was between 2 and 3 grams. Amusic media supervisor Popsy Sham had little to say about the case. 'We have been checking [Vidal's charges] with our legal representatives in Japan but we are still waiting for answers,' she said. 'But we have been told not to disclose any details regarding the case.' Ms Sham said Vidal was still being detained in Tokyo. Soon after Vidal's arrest in February, Amusic said that if the 26-year-old singer was convicted of possessing drugs, the company would terminate its contract with her. Ms Sham said that would be decided after the case in Japan was concluded. Someone convicted of heroin possession could face a jail term of six to 12 months, according to Mr Khattak, but a person convicted for the first time might receive a suspended sentence. On February 24, Vidal and her travelling partner, singer Kelvin Kwan Chor-yiu, were detained on suspicion of shoplifting in the trendy Shibuya district of Tokyo. Police found him in possession of a rolled-up cigarette containing cannabis. The pair, believed to be romantically linked, were held in custody and police later found the packages suspected of containing heroin. Kwan was released on March 27 and returned to Hong Kong the next day, where he was met by narcotics division officers who searched his home but found no drugs. He apologised for what had happened, saying: 'I am sorry. I committed such a big mistake.' Hong Kong police said that they were monitoring the case in Tokyo.
