This is believed to be in response to the small group of protesters who had left the main route of the march and were consequently blockaded by hundreds of police - many provocatively attired in full riot gear, shields and all - in Buccleugh Place for hours.

Although these protesters had done nothing illegal, many of them chose to keep their faces hidden. Police were reluctant to let them leave before having been individually photographed by the Met Police Forward Information Team, and the S60 gave police the power to arrest those who refused to reveal their identities. Two people are believed to have been arrested.
