Police are appealing for information after a 12-year-old girl was injured by a glass bottle during the Glasgow Orange walk.
Kellsie Lynch was left with blood pouring down her face after she was hit by a flying bottle when a fight broke out on Glasgow Green.
She was treated at the nearby Yorkhill hospital in Glasgow, but her injuries are not thought to be serious.
A 22-year-old female who was watching the parade with the girl was also struck and sustained a cut to her hand.
Police are now appealing for witnesses who may have seen the fight.
A spokesperson added: "The girl was watching the Orange walk when a number of people nearby, who were unconnected with her, became involved in a fight which resulted in her being struck with a bottle or similar object."
Eighteen people were also arrested during the march for offences such as disorder and drinking in public.
Labour MP Jim Murphy called for an upcoming march taking place in Edinburgh in the run-up to the Scottish referendum to be cancelled in the wake of the violence, which he said left a "scar on Glasgow".
He added: "I am disgusted. The march before the referendum vote shouldn't go ahead. Better Together [the group lobbying for Scotland to remain part of the UK] want nothing to do with the Orange Order."
Eddy Hyde, Grand Secretary of the Orange Lodge for Scotland, said while he is "horrified" at the injuries the girl sustained, he is confident there will be no trouble at the march in September.
"I don't foresee any problems in Edinburgh. Jim is just scaremongering," he added.
Around 4,500 marchers and 4,000 spectators took part in the Orange walk. Det sgt Ronnie Payne said: "The park was very busy with bands, followers and members of the public on Saturday afternoon.
"I would appeal to anyone who witnessed this incident or has any information which could assist police, to telephone the CID at London Road on the non emergency number 101."
