A ten-year-old boy is among several children arrested in connection with rioting in Co Derry last month.
He was detained along with two 13-year-old boys following searches at several addresses.
They were questioned about disorder in Nailor's Row on 10 August.
The disorder followed the annual Apprentice Boys march in the city earlier that day.
The PSNI said a number of items had been seized.
The children were arrested on suspicion of a number of offences, including riot, and have since been bailed.
Petrol bombs, fireworks and stones were thrown by several youths at police lines during several hours of disorder.
