Martin Deane, Hull and East Riding Green Party:
"I really want to underscore what Simon Pook, the solicitor representing the anti-fracking protesters has written to the Hull area media today [Thursday]. I too am dismayed at the quality of policing of these events, having witnessed it first hand.
"It is clear to me the police have decided not to allow legitimate protest but are simply there to enable the oil industry to do whatever it wants.
"It is also clear that anti-fracking protesters have been targeted elsewhere – such as the arrest of a man busking in Beverley town centre – arrested for singing a song – and forcibly arrested to the consternation of the people and families who witnessed it.
"That's 5 arrests so far – and most of these were avoidable by the police.
"To Humberside police I say: Ratchet it back! Protesters are not your enemy. Enable their right to protest. If they want to walk a lorry in – not just let them, but enable them! Don't make the mistakes Manchester police made.
"The police must enable rightful protest, not kettle it or suppress it. In fact they have a duty under the European Convention on Human Rights."
