Denver deputy who used taekwondo kick is suspended

A Denver sheriff's deputy caught on video provoking a fight with an inmate by using a taekwondo kick has been suspended for 90 days.

The Denver Post reported Wednesday it obtained a disciplinary letter saying Roberto Roena received his suspension July 29 for the April 2013 fight with inmate John Cardenas.

Investigators determined Roena provoked the fight after Cardenas taunted him. Roena is seen throwing a fully extended sidekick toward the inmate's head before putting him in a headlock.

After the fight, Roena wrote in a mandatory report that Cardenas was the aggressor and he threw the kick to defend himself. But investigators said in the letter the inmate did not initially pose a threat.

Attempts by the Post to reach Roena's attorney were unsuccessful.
