Days after being arrested on investigation of sexual assault, choreographer Alex Da Silva was released from jail.

The 41-year-old So You Think You Can Dance contributor was taken into custody by police last Saturday as a result of several rape allegations. Four different victims had accused the dance instructor of assault between 2003 and 2009.

Although the complainants each reported similar stories, the Los Angeles County prosecutors office has not been able to file charges due to a lack of evidence. More women have since come forth with their own stories, so the investigation is not yet closed.

No word yet what this might mean - if anything - for the next season of SYTYCD. The FOX reality series starts up again on May 21.
