When Oswald Varemond's 80-year-old mother intervened and tried to stop him, he allegedly bit off her fingertip and started pulling his own teeth out, a police report said.

On Sunday, police kicked down a bedroom door to find Varemond, 44, straddling his girlfriend, Yolette Lagrandeur, 33, a Haitian recording artist and AIDS activist, The Palm Beach (Fla.) Post reported Tuesday.

A Delray Beach police officer drew his gun and ordered Varemond to put his hands in the air, and officers tried to stun him three times with a Taser, only to have the device malfunction each time.

He was taken to the Palm Beach County Jail on charges of attempted homicide, battery, false imprisonment and resisting arrest with violence, the newspaper reported.

According to the police report, Varemond had asked his girlfriend and his mother, Anne Marie Saget, to pray with him.

When they started to pray, Lagrandeur noticed Varemond "change," she told police. He locked the doors and jumped on Lagrandeur and started biting her on her back and beating her head with the iron.
