A man who threatened "South Park" creators Trey Parker and Matt Stone for depicting the Prophet Muhammad on the show has been arrested on charges he offered to fight for a terror group linked with Osama bin Laden, reports the New York Daily News. 

Zachary Chesser, 20, told police that he tried twice to travel to Somalia to join al-Shabab, but was stopped by his mother-in-law on the first attempt and by the no-fly list the second time, the article says. Many of al-Shabab’s leaders are thought to have fought or trained with Al Qaeda, the story adds.

Chesser isn’t facing charges for his April Website post that threatened the "South Park" creators, and which led Comedy Central to beep out references to Muhammad in the episode. Comedy Central declined to comment on the arrest, the story says.
