The team behind TNT's The Closer, including creator/executive producer James Duff, are working on a spinoff from the hit cop drama starring Kyra Sedgwick, according to The Hollywood Reporter.

TNT confirmed that it has handed out a script order for the spinoff but declined comment on other details.

The Closer stars Sedgwick as a deputy police chief who has a love-hate relationship with junk food. It's unclear whether the untitled spinoff -- referred to in industry circles as The Fixer -- would focus on an existing The Closer character or an altogether new one.

Duff is co-writing the story with The Closer co-executive producer Adam Belanoff and Michael Berchem. Duff and Belanoff will co-write the script and also executive produce with Michael M. Robin and Greer Shephard.

TNT is the latest network to explore a spinoff from its top series. CBS spun twice its hit crime drama CSI: Crime Scene Investigation. ABC's spinoff from Grey's Anatomy, Private Practice, is returning for a second season, while The Cleveland Show, Fox's spinoff from Family Guy, launches in midseason. Additionally, NBC is working on a spinoff from The Office, while Fox and the CW are eyeing potential offshoots from House M.D. and Gossip Girl, respectively.

On cable, Showtime is prepping a spinoff from veteran The L Word, while Sci Fi Channel is piloting a prequel to its signature series Battlestar Galactica.
