The Tallaght club has released a statement expressing disappointment with the crowd trouble that occurred during their Setanta Sports Cup quarter final meeting with Linfield
A flare was thrown onto the pitch during the game, while Shamrock Rovers supporters clashed with riot police inside the ground after a cordon was breached. The Tallaght club has expressed disappointment at the events that occurred in the crowd and stressed that the disturbances were confined to a minority of the support.
"The club is very disappointed by the behaviour of some of our fans at Windsor Park last night," read a statement from the club.
"We brought over 500 supporters to Belfast and the majority of them got behind the team and enjoyed watching the club progress to the semi-finals of the competition.
"Out of the over 500 fans, about 20 caused the problems that occurred last night; we are looking closely at what happened and will take whatever action is necessary."
Linfield supporters clashed with police in Dublin during the first leg at Tallaght Stadium and also engaged in provocative displays and were heard to sing sectarian songs during the second-leg.
However, when contacted, the Irish Premiership club refused to comment on events surrounding the game.
Following the game, Social Democratic and Labour Party (SDLP) MLA for South Belfast Conall McDevitt condemned what he described as 'totally unacceptable' scenes.
He said: "It appears that some Shamrock Rovers fans came to Belfast with the intent to engage in sectarian behaviour. This is totally unacceptable and will be condemned by true football fans across the island.
"Whilst tonight's scenes follow violence by Linfield fans during the first leg in Dublin it remains unjustified and totally unjustifiable."
He continued: "Football has been dogged by sectarianism for decades. Events like tonight must resolve our determination to work together to eliminate sectarianism from football.
"It is a crime in Northern Ireland to engage in sectarian chanting or behaviour during a football game. I trust that the PSNI (Police Service of Northern Ireland) will be reviewing CCTV footage of fans tonight and take steps to prosecute where appropriate."
