(CNN) A Buddhist monk was found dead with his throat slit in a monastery in Bangladesh on Saturday, police said.

Three people have been detained in relation to the attack, state media reported.

The body was discovered by someone bringing him breakfast at the monastery in Bandarban, a district that borders Myanmar.

The victim, Yu Gayinda -- born Maung Sai U Chak (monks acquire a new name at initiation) -- was in his 70s. Police said he was likely killed Friday night.

No one has claimed responsibility for the killing.
