A drunken man stabbed a resident of a monastery in Manton early Halloween morning, deputies said.

The incident at the Monastery of St. John on Ponderosa Way started about 2:20 a.m., officials with the Tehama County Sheriff's Office said.

Deputies said someone called 911 reporting that Michail Pijenko had armed himself with a knife and was intoxicated.

Nearly a half-hour later, they got another call saying 47-year-old Pijenko had stabbed Vasili Romanzov, who lives at the monastery, deputies said. Romanzov was in the bathroom when Pijenko stabbed him twice "unprovoked," deputies said.

Romanzov ran to a neighbor's home for help and was transported to a local hospital for treatment. His condition wasn't immediately known, and it wasn't clear if he was a monk at the monastery.
