Large-scale arrests expected for suspected ringleaders of Dublin riot

Police promise arrests of riot leaders and participants in coming weeks as government seeks to expand use of facial recognition technology

Irish police are expected to make sweeping arrests of suspected ringleaders of Thursday's riot in Dublin and to obtain wider rights to use facial recognition technology to help identify suspects in any future disorder.

The moves come amid mounting pressure on the government and police chiefs over the mayhem on 24 November when an estimated 500 anti-immigrant activists and gangs of youths looted shops, burned vehicles and attacked police, leaving swathes of Ireland's capital resembling a war zone.
