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.
