CONTROVERSIAL cleric Bishop Jonathan Blake was outside New Scotland Yard on Monday to launch his national campaign against police violence and malpractice.

Mr Blake, 52, set up his When No One’s Watching campaign earlier this year after being arrested at his Danson Crescent, Welling, home for allowing his children on the the roof of his home.

He was photographing his children for a school competition.

After his arrest, claims he was manhandled by Bexley police, detained for 24 hours in a dirty police cell and deprived of food and drink before being released without charge.

He says his wife was not allowed to video his arrest and he has no independent evidence of his alleged treatment.

Mr Blake, an archbishop in the Open Episcopal Church, who conducted Jade Goody’s wedding, says his campaign is aimed at ensuring there is an independent record of what happens to people detained by police.

His Four Fingers campaign symbolises its four aims, that police officers, their vehicles and cells should have videoing devices, to be activated when dealing with the public, and that there should be public access to any film.
