The NSPCC has voiced concerns about the increase of convicts being added to the sex-offenders register, as research found that Southwark had the fifth highest rates in London.
Data collected by a joint operation between the Met Police and Ministry of Justice agencies showed that the borough currently has 315 registered sex offender.
Out of the 33 London authority areas, Lambeth had 334 residents on the register; Lewisham had 368; Croydon had 365; and Newham had the most with 385.
The figures were collated by the Strategic Management Board, made up of specialists from the Met Police, the National Probation Service, HM Prison Service and local councils.
An NSPCC spokesperson said: “It’s good that more of these individuals are being put on the list of registered sex offenders but it is worrying that this is such a prolific problem, as many of these offenders will be paedophiles.
“In just ten years, the number of registered sex offenders has risen by 73 per cent and these latest figures mean that nearly one in every 1,000 people in England and Wales is on the register.
“A trend towards more survivors of sex abuse being willing to come forward is encouraging. But there is no room for complacency and it is important to report signs of sexual abuse when they occur.”
The figures were included on in a report released on Monday by the (SMB) Strategic Management Board, entitled the Multi-Agency Public Protection Agencies (MAPPA) Report 2015-16.
Charles Hayward, chair of London MAPPA, wrote in the report to reassure residents of the work being done to monitor former sex offenders.
He said: “As part of the drive to ensure the quality of MAPPA across London, the SMB oversaw a ‘Health-check’ that took place in every borough.”
He added:?“Local managers used this self-assessment as an opportunity to bring the agencies together to identify the strengths and areas for improvement in their borough MAPPA.”
