COLORADO SPRINGS, COLO. -- Witnesses gave police officers conflicting reports about what happened between a teacher and a student that landed the teacher behind bars this week, according to court documents.

Liberty High School teacher Travis Clark, accused of sexually assaulting a student at the Colorado Springs high school, had called on the girl to help him with basketball equipment.

According to documents released this week, the victim said the 32-year-old, a science teacher and varsity basketball coach, asked a girl to help him with basketball equipment, then inappropriately touched her.

The girl, a student in Clark's science class, said she helped Clark three times, and Clark only inappropriately touched her the second time. She said she was excused from class during Clark's free period three times in late February to go to "the cage" where the equipment was. She said nothing happened on day one or three, but Clark was inappropriate on day two.

The girl told officers Clark was putting post-it notes on her butt with messages such as "very nice" written on them. He also tried putting his hand down her pants, but she backed away and told him to stop.

The girl said Clark was nice and very helpful as a teacher and said he kept apologizing when she told him to stop hitting on her and touching her during day two in the cage.

Other than the inappropriate hand contact, the girl denied any sexual contact with Clark. However, when officers interviewed one of the girl's friends, she told a different story.

The friend, who reported the incident to the principle after the girl told her, told officers the girl had said she had oral sex with Clark in "the cage." The girl denied that to officers and the school principal.

Despite the girl's claims that she only helped three times and that nothing happened on day one, video surveillance showed the girl actually helped Clark four times and was seen leaving "the cage" on the first day buttoning her blouse and fixing her skirt.

Cell phone records show Clark and the girl exchanged 250 text messages between Feb. 21 and Feb. 25, talking about helping in the gym, her being grounded and Clark asking her to babysit. The girl told officers Clark asked her to come to his apartment after she became ungrounded. After she told her friend, her friend reported it to the principle thinking the girl would go.

The investigation began March 1 and ended with Clark's arrest June 7. He has since bonded out of jail.
