“Hawaii Five-0” is beefing up its force.

Tom Sizemore is joining the show next season for a multi-episode arc, reports Entertainment Weekly.

He’ll play a former Detroit Homicide Detective who becomes the head of Hawaii’s Internal Affairs division – and you can be sure the hard-edged actor will be giving the “Five-0″ unit a tough time.
