A total of 20 killers are among almost 180 violent or sexual offenders who remain at large despite being recalled to prison, figures show.
In all, 19 murderers, one killer convicted of manslaughter and eight rapists or attempted rapists remained at large at the end of last month despite having their licences revoked before the end of June, the Ministry of Justice said.
The figures for April to June 2010 showed 98 of the 3,702 offenders recalled to prison had not been returned and remained at large with a further 844 offenders who have still not been returned despite being recalled before April.
Of the 942 offenders who remained free, 316 have been on the run for more than five years, the figures showed.
These include 147 offenders guilty of violence against the person and 32 sex offenders, including seven convicted of child sex offences, as well as 124 burglars and 113 robbers.
Most of these offenders (381) were being managed by the local criminal justice board in London, while 93 were in the West Midlands, 41 in Greater Manchester and 29 in both Merseyside and Thames Valley.
