UN highlights ‘psychological harm’ to UK man jailed since 2012 for phone theft

Exclusive: Expert repeats call to review indefinite sentences such as Thomas White's, whose family says now suffers from psychosis

• Number of offenders with IPP sentences recalled to prison soars

A UN torture expert has called the case of a man driven to psychosis after being jailed in the UK for more than a decade for stealing a mobile phone emblematic of the psychological harm" caused by indeterminate sentences.

Thomas White was handed an imprisonment for public protection (IPP) sentence in 2012 for stealing a mobile phone - four months before such prison terms were abolished. He has been in jail ever since after initially receiving a minimum two-year tariff.
