A 12-year-old boy has said he was left with "burning and stinging" eyes when CS gas was deployed by police during Tuesday's junior Orange Order parade.
Police have said two officers were injured and damage caused to a PSNI motorcycle when adults taking part in the parade attacked them.
The trouble apparently developed when an officer tried to stop bandsmen brushing up against and damaging parked cars.
However, parade organisers claim police over-reacted and have criticised the use of CS spray in an area where children were present.
A 26-year-old man arrested at the scene has been charged with disorderly behaviour and two counts of assaulting police.
Speaking at a press conference yesterday, flanked by his father George, schoolboy Christopher King said he was left with stinging eyes from the CS spray used by police.
He claimed an officer reached for the spray and "sprayed it everywhere".
"It hit me in the face and eyes," he said.
"It started stinging and burning so if I tried to open them it really hurt."
He said he went to an optician the following day to check if any damage had been done.
"They said I was lucky I didn't lose my sight," he said.
The schoolboy said despite the experience he would continue to march with the South Belfast Young Conquerors flute band.
His father condemned the actions of the officer involved but said he still supported police.
"I am in the band 23 years and nothing like that has ever happened," said Mr King.
"I wouldn't want it to happen to any other parent, no matter what divide they come from."
Members of the South Belfast Young Conquerors flute band met police to discuss their concerns.
It is thought upwards of 35 people have already given statements to the Police Ombudsman in relation to the incident.
The band also condemned threats made against a community police officer who has been forced to review his personal security after his name, picture and home address were posted online.
The post on the PUL Media Facebook page was later removed.
A spokesman for the band said: "We wish to express our clear and unequivocal condemnation of a police officer's details being posted on social media platforms."
It said in its 40-year history it had only sought to "maintain the highest standard of dignity and musicality" and would make no further comment until the ombudsman's investigation is complete.
