A post on RevolutionMuslim.com warned the creators of the animated comedy, Trey Parker and Matt Stone, over their controversial depiction of Prophet Muhammad dressed up in a bear suit.
The message referenced Dutch filmmaker Theo Van Gogh, who was shot by fundamentalists who objected to a movie he made about the treatment of Muslim women. The post also contained the address of Comedy Central's New York office and the California production studio where the show is made.
The episode featuring the religious figure aired in America on Wednesday, but the controversial character was blocked from view by a 'Censored' banner and mention of his name was bleeped out.
A spokesman for the Comedy Central network confirmed they instigated the changes, not the South Park producers, saying, "I can't go into the thinking behind it, but I can confirm it was Comedy Central that inserted the bleeps and not South Park."
A statement from Parker and Stone, reads, "In the 14 years we've been doing South Park we have never done a show that we couldn't stand behind. We delivered our version of the show to Comedy Central, and they made a determination to alter the episode.
"(South Park character) Kyle's customary final speech was about intimidation and fear. It didn't mention Muhammad at all but it got bleeped... We'll be back next week with a whole new show about something completely different and we'll see what happens to it."
