The actor announced via Twitter that last Friday was his final day of filming after 15 seasons on the L&O spin-off. He originated the role on the flagship series.

Showrunner Warren Leight also marked Florek’s final episode on Twitter with a series of photos.

Earlier this season, Richard Belzer’s Sgt. John Munch retired, with the actor being downgraded from series regular status to recurring player.
