MINNEAPOLIS — A Minnesota man threatened his daughter with an AK-47 rifle because she was getting two B’s in school rather than straight A’s, according to a criminal complaint filed Friday.

Kirill Bartashevitch, 51, of St. Paul, was charged in Ramsey County District Court with two felony counts of terroristic threats after allegedly pointing the gun at his daughter, 15, and his wife during an argument at their house Jan. 13.

The incident came to light at Central High School when a social worker received a report from a parent who said she had been monitoring her son’s electronic communications when she saw a message from the girl. Police were notified of the incident Jan. 17.

Bartashevitch had recently purchased the rifle out of fear such guns soon will be banned, the complaint said.

He admitted to St. Paul police that he had pointed the gun at his wife and daughter, but said it wasn’t loaded and he had checked the chamber beforehand.

The mother verified her daughter’s account and said that when she tried to protect the girl, her husband pushed her to the floor.

The girl has been taken to a shelter, the complaint said. Bartashevitch, an employee of Minneapolis Public Schools, was in custody with bail set at $20,000.
