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 . At the time , all three celebrities publicly denied appearing in the tapes , saying the people in the footage just looked like them . The videos sparked protests by conservative Islamic groups and others around the country condemning the celebrities . When the district court judge read the sentence in the packed courtroom Monday , hundreds of hardliners who gathered outside the courthouse booed . `` Ariel is guilty , '' some chanted , as about 1,000 anti-riot police personnel stood guard . `` He should have gotten at least five years , '' said Chep Hernawan , head of the Alliance of Islamic Movements . `` We 're extremely disappointed . '' Noted feminist and author Julia Suryakusuma said the protests are sending the wrong message . `` This is also sending out the message that if you 're loud enough , then you 'll get heard and that 's not the way it should be , '' she said . Later Monday , the court sentenced an employee of Peterpan 's music label to two years in prison . Prosecutors said the employee , Reza Rinaldi , was the one who uploaded the videos on the Internet .
NEW : The employee who uploaded the videos is also sentenced . Comment: Ariel will also have to pay a $ 28,000 fine . The frontman of `` Peterpan '' is the first high-profile offender of the country 's pornography law .
