Not exactly the homecoming Conor McGregor imagined ...
The UFC star has finally returned to Ireland after that violent bus attack in Brooklyn ... but instead of soaking up the spotlight (as usual), he shot photogs the 1-finger salute.
As we previously reported ... after McGregor was released from jail on April 6th, he flew to the Bahamas for a little R&R with his girlfriend Dee Devlin and his kid Conor McGregor Jr.
But now, Conor has returned back to Ireland ... and he doesn't look too happy.
