Pop singer Janice Vidal has finally broken her silence about her twin sister Jill, who was arrested in Japan with fellow singer Kelvin Kwan Chor-yiu last month on suspicion of shoplifting and drug possession. Speaking to the press this week, Janice admitted that her younger sister had done 'something wrong' and that she was hoping to put things straight by releasing an anti-drugs pop song titled 999. A senior executive from the singer's record label said the song was composed for Jill (near right) originally, but Janice (far right) would now record it. Until recently the lyrics had not been written, but both the company and Janice had agreed to make it an anti-drugs message for young people, urging them not to be afraid of calling the police when things went wrong. 'Thanks for everyone's concern for Jill,' Janice said. 'At the moment, I am like any one of you. I can do nothing but wait. But as an elder sister, a singer and a public figure, I felt I should do something. 'I'm not very good at talking and I don't want to turn explanations into excuses, but as a singer I would like to prove everything with my new song.' Janice was nevertheless reluctant to answer questions about whether she too had taken drugs. The song seems to have captured some of the things that Janice wanted to say to her younger sister. The lyrics are: 'Stop it boy/ Stop it girl/ I think you're cursed/ I love you but I gotta shout loud when you're out of line ... I love you but I know eventually you'll get through/ Wash your face/ Stop wasting time/ You've got to rewind / Call 999.' Meanwhile, Jill Vidal said this week through her lawyer that she was too ashamed to see her family members while she was in jail and had asked them not to visit.
