METRO Broadcast has been fined $10,000 for carrying a banned advertisement for a hair-treatment clinic, the Broadcasting Authority said yesterday. The clinics were deemed unsuitable for advertising on the air under radio programme standards. The authority also warned ATV about a Chinese film with a homosexual scene, and STAR TV was criticised for too much violence in a movie. The hair-clinic promotion - aired during the Metro radio programme Jo-Good Morning-Sun on September 18 - was not clearly distinguishable as an advertisement, the authority said. It said Metro had been given six serious warnings for indirect advertising in programmes this year. The station has said efforts will be made to prevent recurrences and blamed some of the mistakes on staff changes. An authority spokesman said last night that a group of medical professionals who were consulted over the standards had advised that hair-treatment clinics should not be advertised on radio. He would not elaborate on the reasons for the ban. Three other advertisements on Metro in September and October also attracted a warning, a strong advice and an advice from the authority. Sanctions range from the issuing of an advice at the lower end of breaches of standards, while warnings and fines are imposed at the upper end. ATV's Chinese-language channel received two warnings. The film, Chez N'ham, was deemed to have undesirable expressions with sexual innuendos and a homosexual scene shown during family viewing hours. And advertising material for electrical appliances was shown during the Street Chat programme. A warning was given to Hutchvision, the licensee carrying STAR TV's signal, for showing too much violence during the film Story of Ricky, the spokesman said. TVB received strong advice over an advertisement for a telephone company that had made an unsubstantiated factual claim over its charges. A promotion for the film Child's Play II, showing a possessed doll wielding a knife, was considered potentially unnerving for children and advice was issued to TVB.
