A 48-year-old man has been charged with disorderly behaviour following disturbances in Londonderry in which two policemen were injured.
Four other males arrested on Tuesday have been released on bail pending further enquiries.
The accused is to appear in court in the city next month.
The officers were struck with bricks during the trouble at Nailors Row, close to the Bishop Street-Fountain interface, on Monday evening.
Petrol bombs were also thrown by a crowd of about 20 people, most of whom were teenagers.
"The trouble went on for at least a couple of hours, having started at about 1915 BST," said a police spokeswoman.
