Bogor. A 35-year-old man with a presumed mental disorder was beaten to death by his neighbors in Bogor district on Friday night after he disturbed a religious celebration at the local mosque and threatened people with a machete.

According to a spokeswoman for the Bogor District Police, Adj. Comr. Ita Puspalena, the man, Utis, interfered with an event held to mark maulid, the birthday of the Prophet Muhammad, in the Jasinga subdistrict's Jugalajaya village.

Ita said the man first damaged the mosque's door and started messing around with furniture inside, at around 7 p.m., for reasons unknown.

Utis's parents said they locked him inside the house after the 7 p.m. incident, but he somehow managed to escape and returned to the mosque at about 11 p.m. This time, the man was carrying a machete and was threatening people at the mosque, the police spokeswoman said, which led to a severe beating.

"The victim suffered serious injuries to the back of his head," Ita said on Saturday. "He also had wounds on his cheek and temple, and a number of teeth were missing."

Several people tried to interfere to halt the violence, but Utis could not be saved and died on the way to hospital.

According to the victim's parents it wasn't the first such incident their son was involved in.

They said they had taken Utis to hospital for therapy previously, but couldn't afford to continue the treatment.
