CINCINNATI  Two teenagers with long criminal records have been charged with torturing a young woman for at least six hours inside her home in rural southwestern Ohio.

The victim, Ashley Clark, 18, was found bound, gagged and bleeding on Friday by police officers and her mother, who had called 911 when she returned from work and found the house, in Hanover Township, ransacked.

Ashley Clark told the police she had been beaten throughout the day, sometimes with a baseball bat. The police also said her hair had been cut off. She had severe bruising on her hands, arms and face and was bleeding from her face and forehead, according to the police.

The abuse included dousing Ms. Clark in the shower and then forcing her to walk barefoot through snow. Her pleas to her assailants not to strike her in the head because she had had brain surgery went unheeded, she told the police.
