A Miami man who suspected his girlfriend of being unfaithful tortured the woman for more than three hours, police said.

Roman Rengifo had been drinking when he began beating his girlfriend Saturday evening, according to police. They said he accused her of cheating and started kicking and punching her. Then he threatened her with a knife and dunked her head in a bathtub filled with water several times.

Eventually, police said Rengifo tied the woman up with cords and threw her in a closet. When he saw that she was trying to escape, he tied her to a bedpost.

After Rengifo left the apartment, the woman said she was able to free herself and call for help.

Authorities were still looking for Rengifo on Sunday.
