Fredric Lehne has joined the cast of Chicago Fire as a recurring guest star, EW has learned exclusively.

Lehne will play Deputy District Chief Ray Riddle, a gruff, hard charging fire chief above Boden (Eamonn Walker) who is one of a new breed of politically savvy climbers in the CFD. He’s gunning for the top spot of Fire Commissioner, and he doesn’t care if Firehouse 51 ends up as collateral damage in the process.

The actor — whose extensive credits include Lost, Bones and Criminal Minds — joins other season 4 additions Steven R. McQueen as a new candidate, Brian White as the new Squad lieutenant when Severide (Taylor Kinney) is demoted by Riddle, and Rachel Nichols as a love interest for Severide.  

Chicago Fire returns Tuesday, Oct. 13 at 10 p.m. ET on NBC.
