The bear is believed to have been wounded by a hunter, RIA Novosti reported. The police officer said he had to open fire when the bear threatened to maul him and tore his clothes.
The ursine break-in occurred Friday in Primorye Territory.
"The animal became aggressive, and we had no other way out than to shoot," a police spokesman said. "It's good no one in the village was injured."
A local agricultural school took custody of the carcass for study.
