A 17-year-old from Killeen is in the Bell County Jail after reportedly confessing to having sex with an 11-year-old girl.

KWTX reports that Korben Michael Czibik was arrested Tuesday and is being held in lieu of $100,000 bond.

The girl's mother told police Czibik was staying the night with her son Saturday in her home in Killeen. Around 7:30 Sunday morning, the woman went to check on her daughter but discovered she wasn't in her room.

She then noticed the light in the bathroom was on and the door was unlocked. When the woman opened the door, she saw her daughter sitting naked on the toilet and caught a glimpse of Czibik's face just before he slammed the door shut and locked it.

The mother told authorities she demanded that they exit the bathroom, at which point Czibik opened the door and said, “ I accept full responsibility for my actions.”

The child later confirmed that Czibik had intercourse with her in the bathroom. Police say Czibik admitted to the sex act and said he thought the girl was 13.
