Police in Derry say it's lucky no one was seriously injured after two petrol bombs were thrown over the city walls last night.
The area, close to the Memorial Hall, was busy with people after a parade in the city.
Attending officers were also attacked by people who threw up to 20 petrol bombs and other missiles in the Fahan Street area.
The PSNI is investigating and are appealing for witnesses to contact them.
Meanwhile, five people remain in police custody following yesterday's Apprentice Boys parade.
Officers are investigating the behaviours and symbols displayed by one band.
They're also investigating a number of people in relation to an un-notified counter protest.
