LAKE MARY, Fla. -- The owner of a Lake Mary dance center was arrested on Friday, accused by police of providing Ecstasy to underage girls and having sex with them.

George Fagan, 38, the owner of Giorgio's American Dance Center in Lake Mary, was charged with sexual assault and sexual battery on at least seven minors.

Fagan was arrested on Friday while instructing a class after a 16-year-old dancer came forward in December, claiming that she was given drugs and had sex with Fagan.

The dancer who came forward had taken classes at the center for nearly 10 years, detectives told Local 6 News.

"That's what detectives say, that (Fagan) would groom the girls until at some point he would decide for himself that he wanted to go ahead and introduce them to the illegal drugs and to sex," Local 6's Jamie Guirola reported.

The 16-year-old said she did drugs and had sex with Fagan at least 50 times, according to detectives.

She provided names of other alleged victims to authorities, who said they believe other victims exist.

According to Fagan's Web site, Fagan has been the leading dance teacher and choreographer in Central Florida since 1994. It says he has toured with Paula Abdul, Keith Sweat, CeCe Peniston and others.

The Web site also says Fagan "shares his talent and love of dance with school children through his American Street Dance program which tours most public schools in Seminole, Orange, Osceola and Brevard counties."
