YANGON (REUTERS) - A Myanmar court on Thursday (Oct 6) sentenced a Dutch tourist to three months in prison and a fine after he unplugged a public address system that was relaying a Buddhist sermon, his lawyer said.

Klaas Haytema, 30, was arrested after he entered a community hall in the central city of Mandalay on Sept 23 and disrupted a recitation by Buddhist laymen.

Haytema told a court hearing on Tuesday (Oct 4) he was unaware a religious ceremony was in progress, but disconnected the hall's loudspeakers because they were disturbing his sleep, said Mr Hla Ko, a Myanmar lawyer who volunteered to represent the Dutchman.

Sermons broadcast through the night using loudspeakers are a common practice in the South-east Asian country, where the vast majority of people are Buddhists.

A judge convicted Haytema of "causing disturbance to an assembly lawfully engaged in the performance of religious worship," Mr Hla Ko said.

"He was found guilty under Section 296 of the Penal Code and sentenced to three months in prison," the lawyer said, adding that a fine of about US$80 (S$109) was also paid on Haytema's behalf for breaching Myanmar's rules on respecting its culture.

"I plan to lodge an appeal for him against the verdict," Mr Hla Ko added.
