DJ Whoo Kid Was Busted Over Child Support

DJ Whoo Kid had an abrupt exit from work Monday ... after cops showed up and took him out in cuffs.

Nassau County Sheriff's paid Whoo Kid a visit at the SiriusXM office in Manhattan, and nabbed him on an outstanding family court warrant ... law enforcement tells TMZ.

Unclear what the warrant was for -- child support cases are confidential. Sources close to Whoo Kid tell us he had a warrant out for missing a court date ... the computer showed he was also 2 years behind on child support.
