Joshua Allen, the winner of “So You Think You Can Dance” season 4, has been charged with domestic abuse and could face over a decade in state prison, the L.A. County D.A. said on Thursday.

Allen potentially faces two felony counts of willfully injuring his girlfriend after a prior conviction and one felony count of assault with a deadly weapon, a glass vase.

According to the authorities, Allen was convicted of injuring his girlfriend in January, and was issued a criminal protective order that kept him from communicating with her.

The prosecutors allege that Allen assaulted and strangled the same woman a few months later, on April 13, and attacked her again on June 19.

The woman allegedly ran to a coffee shop to escape, and Allen threw a glass vase at another woman who was trying to help the victim. Prosecutors added that Allen also attacked a man and vandalized the coffee shop.

If convicted as charged, Allen faces a maximum sentence of over ten years in state prison. Prosecutors will request $270,000 bail.

Since winning “So You Think You Can Dance” in 2008, Allen’s credits include “Step Up 3D” and the 2011 remake of “Footloose.” The dance competition show is currently in its 13th season.
