Former Sunderland defender Dan Casey has joined Bohemian FC.
The 19-year-old, who can play at right-back or centre back, made six starts and seven substitute appearances for Elliott Dickman's Under-23 side last season.
Casey spent four years at Sunderland but has now signed for Bohemian FC having impressed in a friendly against FC United of Manchester on Saturday.
Bohemians manager Keith Long said: "He was a very sought-after player before going over to Sunderland.
"I'm delighted to sign him. He's a big, powerful lad. He's a player who I believe will be a good addition to the squad.
"We've got someone coming home who is hungry to succeed and who wants to play.
"He's had four years as a young pro at Sunderland and has played at Under-23 level there. Now he wants first-team football.
"I think we've got someone who feels he's got a bit of a point to prove and I believe he will do that at Dalymount."
A graduate of St Joseph's Boys AFC Casey has represented Ireland at international level up to Under-19 level.
