Myint Aung, a legal official at the Kantbalu township court, says Hsan Min Oo was found guilty and sentenced yesterday after a speedy trial.
Myint Aung says the defendant confessed to the crime and did not ask for a defence lawyer.
The August 24 violence started after a crowd surrounded a police station in Htan Gone village, demanding that Hsan Min Oo be handed over.
When officers refused, the crowd rampaged, destroying 40 Muslim-owned shops and businesses and leaving hundreds of people homeless.
