In a re-run of last Monday, police tolerated a peaceful demonstration for an hour, then leafleted the crowd to tell them their presence was illegal under the new Serious Organised Crime and Police Bill.

A squad of around twenty then moved in and gave individuals verbal warnings, prior to snatch squads removing them to waiting vans.

It was apparent that they had targeted demonstrators with banners - the act of separating protester from banner seemed to be part of the theatre. Several people announced they'd be back next Sunday with banners in tow, a fact quickly noted down by eavesdropping officers.

More demonstrations are scheduled in Parliament Square, check Protest.net for details.
