A woman who decapitated her pet rabbit and then threatened her roommate was arrested by Salt Lake City police Wednesday.

Just before 9 p.m., a 26-year-old woman cut the head off her rabbit and then showed it to her roommate, according to a Salt Lake City police watch log.

That led to a fight, and the woman grabbed their dog while still holding the knife. She also held the knife to the chest of her male roommate, who then wrestled the knife away from her, according to the report.

The woman was found on the roof of the residence, near 800 East and 1300 South, and was arrested without further incident. She was booked into the Salt Lake County Jail for investigation of aggravated assault and animal cruelty.
