HOUSTON -

Harris County sheriff's deputies arrested Syrjuan Benson, a 27-year-old registered sex offender, who is now facing an indecency charge after being caught with a 13-year-old girl.

"She met him through a friend at school, he posed as a 16-year-old boy," said the 13-year-old's mother, whose identity Local 2 is hiding to protect her daughter.

The mother told Local 2 Benson broke in through a bedroom window. She caught him at 4 a.m. hiding in a closet wearing boxers.

"We got into a scuffle inside the house," said the mom. "I hit him in the face three good times and he fell to the floor."

She held him there until the police arrived.

"He told the police his name was Chris and that he was 16. Come to find out he was a registered sex offender," she said. "Twenty-seven-year-old sleeping with my 13-year-old."

Court documents indicate Benson was convicted of sexual assault just a few months ago.

The girl's mother said Benson has been hanging around her daughter's school telling all the girls he's a teenager.

"There's no telling how many more he's done this to and hopefully if anyone else's child has been sexually assaulted, they will come forward," the mother said.

Benson is being held inside the Harris County Jail without bond. His next scheduled court appearance is at the end of the month.
