A 13-year-old boy was one of three people arrested in Belfast when trouble flared after a loyalist band defied a ruling not to march past a Catholic church yesterday.
Seven police officers were injured in yesterday's disturbances - none seriously.
The Young Conway Volunteers band had been banned from parading past St Patrick's Church on Donegall Street in Belfast.
That was after they were filmed playing an allegedly sectarian song there during Twelfth of July demonstrations.
Violence broke out in the area as the Shankill Road band marched past the church yesterday.
A number of bands played music outside the Catholic church, breaching a ruling by the Parades Commission.
Police were attacked when they tried to keep nationalists opposed to the parade and loyalists apart.
Bottles were thrown from both sides during the trouble.
A female officer required hospital treatment after suffering a head injury.
Today, police said they'd arrested a 13 year-old boy on suspicion of riotous behaviour, and a 38 year-old man on suspicion of disorderly behaviour and provocative conduct.
And they charged an 18 year-old man with disorderly behaviour and assaulting police.
He's due to appear at Belfast Magistrates Court next month.
