Two football fans have been arrested after trouble erupted at a Linfield match in Dublin last night.
The men were held during clashes with gardai at the Setanta Cup tie between Shamrock Rovers and Linfield at the Tallaght Stadium.
A garda was thrown from his horse outside the stadium. The garda was taken to nearby Tallaght Hospital as a precaution. However, his injuries are not believed to be serious.
The violence flared after a section of Linfield supporters managed to run a Union flag up a flag pole inside the ground.
Witnesses said a pocket of the Belfast club's fans clashed with gardai and security as they waited to go home.
Shamrock Rovers supporters had to be cleared from the pitch after a goal from Ciaran Kilduff.
There were also reports of sectarian chanting from both sets of fans throughout the game, which Linfield lost 4-1.
It was the first meeting between Rovers and Linfield since a 1984 European Cup tie.
The teams meet again next Monday at Windsor Park in a clash which is expected to be accompanied by a heavy security operation.
