Bandung, Indonesia (CNN) -- Indonesian pop star Nazril "Ariel" Ilham was sentenced to three and a half years in prison Monday for his involvement in sex videos that authorities said featured him and two other top Indonesian celebrities.
As part of his conviction under the country's anti-pornography law, Ariel will also have to pay a $28,000 fine. Prosecutors had asked for a five-year jail sentence.
He will appeal, his lawyer said, adding that there was no clear evidence that Ariel distributed the videos.
Ariel, the frontman of the rock band "Peterpan," was the first high-profile offender of the pornography law that went into effect in 2008 and carries a maximum penalty of 12 years.
The first video surfaced on several websites last year and went viral through social networking sites Facebook and Twitter. It allegedly featured Ariel and girlfriend Luna Maya -- a model and TV journalist who interviewed Hillary Clinton on her show "Dahsyat" during the U.S. secretary of state's visit to Indonesia in 2009.
After the release of the second video allegedly featuring Ariel and Cut Tari -- a soap opera star and TV journalist -- the term "Ariel Peterporn," a spin on the singer's name and his band, became a top trending topic on Twitter. CNN
