50 Cent was arrested in St. Kitts in the Caribbean Saturday night … for using a word that’s apparently illegal there … ‘motherf*****.”

https://www.instagram.com/p/BHG-cQ4A0JE/embed/captioned/?v=7Sources tell TMZ, 50 had been warned not to use profanity during his performance in front of 40,000 people.  We’re told the DJ didn’t have a clean version of his set, and 50 didn’t pull the mic away from his mouth when he roared, “motherf*****” … and that was enough to get him arrested.

Cops showed up after the performance and took 50 to the station, where he was booked for using profanity in public.  It’s a minor offense, but he has to stick around until Monday when he’ll go to court and pay a fine.

The same thing happened to DMX in 2003.
