A choreographer who worked on US TV hit So You Think You Can Dance has been jailed for a decade.

Gossip Cop reports that Alex De Silva is charged with raping a woman in 2002 and assaulting another in 2009. He will also have to register himself as a sex offender.

In September last year, a jury convicted him of the rape and the assault with intent to commit rape, but stalled on four additional counts of violence, including the alleged rapes of two other women in 2004 and 2005.

Kathleen Kennedy, judge in the Los Angeles Superior Court, has dismissed those other charges.

De Silva worked on the first four seasons of So You Think You Can Dance, hosted by Cat Deeley, and was arrested back in 2009.
