An Indonesian man was sentenced to jail in Malaysia for possessing graphics and videos linked to the Islamic State (IS) terrorist cell.

Mohammed Al-Arshy Mus Budiono, 24, pleaded guilty to possessing terrorism propaganda materials on October 17 at the Kuala Lumpur High Court, the New Straits Times reported.

During the trial, it was revealed that Budiono had nine videos and five images related to the terrorist cell on his cellphone. Prosecutor Munirah Shamsudin asked the court to penalize the defendant to a point where he might learn a lesson.

Budiono’s lawyer Zaini Bakar pleaded for leniency, claiming that Budiono works to support his four siblings who are students in East Java. She also claimed that her client did not know his actions were against the law.

Judge Mohammad Nazlan Mohammad Ghazali sentenced Budiono to 18 months’ imprisonment and advised him not to get involved in illegal activities, especially terrorist activities. He also said that crimes linked with terrorism threaten national security and the system of parliamentary democracy.
