There were scenes of chaos outside the Arndale on Sunday afternoon (November 27) after a large group of 'travellers' and young people reportedly 'set off alarms', 'fireworks' and ran 'up and down the tram tracks'.
Witnesses reported hearing alarms sounding in the Arndale shopping centre, with 'hundreds' of teenagers gathering outside and blocking tram lines.
According to councillor Pat Karney, spokesperson for the city centre, there were huge groups of teenagers and children who were causing 'havoc', with some reportedly thrown out of the busy shopping centre by security after alarms and fireworks were set off.
