Law & Order SVU star Richard Belzer is calling on the cop show's makers to explain why they are cutting him from the series.

Belzer's character Sergeant John Munch has slowly disappeared from the show's plotlines, causing fans of the grizzled cop to protest online.

And the 63-year-old actor is joining them, telling PageSix.com, "It's mystifying to me. And I have to admit my feelings are slightly hurt.

"But I do feel flattered my fans miss me."
