On the Chicago P.D. episode “Fathers and Sons,” while undercover, Ruzek (Patrick John Flueger) is surprised to bump into his father Bob who’s working for Spiro, the owner of a strip club (and a suspected drug dealer). Later, when Ruzek visits his father at his home, he asks Bob why he’s working for Spiro. His father says, “I’m getting paid to work security.” Ruzek isn’t totally convinced his old man is working on the up-and-up. Last time Bob showed up on Chicago P.D. was in the 2015 episode “Disco Bob.”
Ruzek’s dad is portrayed by actor Jack Coleman. He’s known for his roles on Heroes (Noah Bennett), Castle (Sen. Bracken), Scandal (Daniel Douglas Langston), Burn Notice (Andrew Strong), The Office (State Sen. Rob Lipton), The Vampire Diaries (Bill Forbes), Dynasty (Steven Carrington), and Days of Our Lives (Jake Kositchek), among others. Chicago P.D. airs Wednesdays at 10 pm on NBC, right after Chicago Fire.
