Among the criminals who were granted such a possibility were individuals convicted of the rape of both male and female minors, incest and taking indecent photographs of their underage victims, the broadcaster reported.
Over half of applications submitted nationwide under the Supreme Court ruling were successful, although the appeal results differ by police district, the figures showed. Specifically, 90 percent of requests were approved by North Wales Police, and none by Dyfed-Powys Police.
As of March 31, 2015, a total of 49,466 sex offenders were registered in Britain, according to official police statistics.
