A judge in England has questioned the wisdom of social workers placing a vulnerable teenage girl alone a flat and left almost unsupervised in inner city Bristol – leading to her being raped and prostituted by Somali drug dealers.

Three men have been arrested by police investigating a paedophile ring which led to vulnerable schoolgirls being drugged, raped and sold into prostitution.

Police and social workers apologised today for not protecting vulnerable schoolgirls who were sexually abused and exploited by a paedophile ring in the UK.
