The owner of BQuick Brazilian Jiu Jitsu was arrested Monday and charged with sexual assault of a child.

Samuel David Lewis, 23, is accused of having sex with a 14-year-old female who had been attending Jiu Jitsu classes with Lewis since May or June 2013.

The two reportedly had sex twice - both times inside the bathroom at the club, according to an arrest affidavit.

The victim told investigators the two began spending time together outside of class and developed feelings for one another.

On Christmas Eve, they had breakfast together, then went to the gym where they had sex for the first time. The second time was on New Year's Eve, according to the affidavit.

Lewis remains incarcerated at the Erath County Jail on a $25,000 bond.
