The main Apprentice Boys' parade in Derry took place today with 10,000 marchers accompanied by 150 loyalists bands.
The parade passed off without any incident, although at one point a number of men draped a banner from a building overlooking the route of the march calling for political status for republican prisoners.
The new deputy chief constable of the PSNI, Paul Leighton, praised the organisers of the parade and the nationalist residents in Derry.
He said the peaceful nature of the march was evidence of the progress that could be made through dialogue and he said there were lessons to be learnt from Derry for other controversial marches.
Earlier, two people were arrested after disturbances in Derry ahead of today's Apprentice Boys' parade.
The arrests followed the hijacking of an articulated lorry which was later set alight in the nationalist Bogside area.
Four cars were also burned out by groups of youths and there have been a number of stone-throwing incidents.
