Fans clashed on the pitch after Celtic knocked Rangers out of the Scottish Cup on penalties.
Some Celtic fans ran on to the field at the final whistle to celebrate after their team secured a 4-2 win in the shootout, and a place in the competition’s semi-finals, after a goalless draw.
A number of Rangers supporters also ran on to the pitch at the end of the game.
Missiles were thrown, and there appeared to be some minor skirmishes, before order was restored by police and stewards, who formed a barrier between the two sets of supporters.
Celtic’s team, backed by 7,500 fans at one end of the stadium, had not registered a shot on target during 120 minutes of action in Glasgow.
The Scottish Football Association has condemned the pitch invasion.
A statement read: “The Scottish FA condemns the behaviour from supporters entering the field of play following today’s Scottish Gas Scottish Cup Quarter-Final at Ibrox Stadium.
“An investigation will be carried out immediately in line with the Judicial Panel Protocol.”
