Help needed
 
Were you a protestor or filming at the Student demonstration on 9th December 2010. Or, do you recognise any of the protestors or camera people in this film. We are looking for witnesses to the arrest of two brothers who were wearing "V for Vendetta" masks - they can be seen to the left in the photo named "masked students". This all happened around 3.30pm to 4pm at the corner of Victoria Street and Broad Sanctuary.
 
If you think you can help can you email me on woodywood2@blueyonder.co.uk.
 
Thanks
