Police identified the victim as Bandara (33) and said he was part of a group of Sri Lankan pilgrims, who arrived here enroute to Colombo after visiting various holy sites including Gaya.
The Buddhist priest in saffron robe was repeatedly assaulted by unknown persons, police said, adding, cases had been filed under different sections of IPC including "voluntarily causing hurt."
The assailants had fled the spot and a hunt had been launched to nab them.
The incident comes in the backdrop of surging emotions in Tamil Nadu over the Sri Lankan Tamils issue following pictures showing slain LTTE chief V Prabakaran's 12-year-old son allegedly being killed in cold blood.
