Timothy Vidal, a 6th Degree Black Belt and former master instructor at Tiger Rock Martial Arts in McKinney remains in the Collin County Jail. Vidal, 34, turned himself in earlier this month after police in Allen began investigating an assault involving a 16-year-old girl he instructed.

After news began circulating about the accusations against Vidal in Allen, a second girl in McKinney came forward and said Vidal had assaulted her too. The girl claims the sexual assaults happened several times starting when she was 14-years-old.

Vidal was fired as a martial arts instructor after it was learned one of his accusers was one of his students. Marv Conway, the owner of Tiger Rock Martial Arts, told CBS 11 News that Vidal confessed to him.

When he was initially arrested Vidal was being held on a $75,000 bond, but after having a second charge was leveled against him this week that amount was increased to $225,000.
