Two men have been arrested for public order offences during clashes with Gardaí at the Tallaght Stadium in Dublin tonight.
It happened during the Setanta Cup tie between Shamrock Rovers and Linfield.
A garda was thrown from his horse outside the stadium.
The trouble flared after a section of Linfield supporters managed to run the Union Jack up a flag pole inside the ground.
Shamrock Rovers supporters had to be cleared from the pitch after a goal from Ciaran Kilduff and there were also reports of sectarian chanting from both sets of fans throughout the game.
