SEVENTY people a month on average die in or shortly after detention, according to results of a survey revealed today.

More than 110,000 people in Britain are detained on any given day in prisons, immigration centres, secure children’s accommodation and psychiatric hospitals.

The true total may be higher as not all government and official agencies provided complete and comparable data and the analysis does not cover police custody, researchers at the  National Preventive Mechanism (NPM) said.
