Sports Minister Carál Ní Chuilín has said bigotry and intolerance have no place in football.
The Minister said: “Sectarianism, from whatever quarter, is totally unacceptable. It has no place anywhere in our society, and certainly not in sport, which should unite rather than divide. Sectarianism is a manifestation of the worst kind of bigotry and racism.
“It is unacceptable that a minority of supporters engaged in this behaviour on Tuesday night. This culture of sectarianism must be confronted.
“I acknowledge the work of Linfield and Cliftonville football clubs in their communities and on cross-community initiatives, and also that the vast majority of fans are only interested in the enjoyment of sport.
“However, Tuesday night’s outrageous behaviour is an indication that we must now all redouble our efforts to promote inclusion, equality and respect.”
