The Police Ombudsman has said there will be no prosecution over an officer's use of CS spray during a junior Orange Order parade in Belfast last March.
However, an officer is facing prosecution for driving a police Land Rover dangerously.
Claims were made that children as young as six were exposed to CS spray at the parade on the Ormeau Road. It was alleged two of the youngsters had to be treated in hospital for the effects of the spray.
The PSNI said the spray was deployed after two officers were attacked by adult band members.
In a statement, the police watchdog said: "No prosecutions have been directed in respect of the use of CS spray or handheld batons by police officers." It added: "The PPS has now directed that one officer should be prosecuted for dangerous driving in relation to the manner in which he drove a police Land Rover."
