Sean Quinn's nephew, who has been on the run from Irish police for over a week, attended a GAA match between Belcoo and Tempo in Kinawley on Friday night.
He was at the game with his father, Peter snr, former president of the GAA.
It's understood he socialised with friends in Enniskillen after the match.
Both Peter and Sean Quinn junior were sentenced to three months in jail for contempt of court at Dublin's High Court, but Peter, former head of the Quinn family's International Property Group (IPG) failed to turn up after calling in sick and a warrant was issued for his arrest.
While he remains in Northern Ireland the PSNI are unable to forcibly return him to the South without a European Arrest Warrant.
