Alex DeSilva might want to rethink what he can and cannot do.

The 41-year-old So You Think You Can Dance choreographer and performer was arrested on Saturday for four counts of sexual assault that took place between May 2003 and March 2009.

According to the LAPD, all of the victims were his students at the time. DeSilva allegedly lured them to his homes in North Hollywood and Van Nuys, Calif., and raped them.

Bail has been set at $3.8 million.

Police believe there may be other victims.
