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.
When Whoo convinced the judge he was up-to-date on support payments, they let him go.
