Police had 'No power' to take 'Kettled' Woman's Details BBC News, 18/06/13
Police officers who took the personal details of a woman "kettled" during a trade union rally in 2011 acted unlawfully, the High Court has ruled. The court ordered the Metropolitan Police to delete records of Susannah Mengesha and film and photographs taken of her at the demo. Her details were taken while she was contained by police while a legal observer during the London protest. A judge ruled officers had no powers to film her or take her name and address.
Ms Mengesha, a law graduate, was part of a group of protesters who were contained by police near London's Piccadilly Circus for two hours on 30 November 2011 at a trade union march against public sector pension cuts.

Before being allowed to leave, police filmed Ms Mengehsa and made her hand over personal information.
