Sex offender compliance with the notification requirements of the Sexual Offences Act 2003 is high at around 97 per cent. in Northern Ireland. Notifications are recorded by the police on a live database and the number of unregistered offenders in breach of the requirements may therefore fluctuate on a daily basis. A search of the database to provide the information in reply to the hon. Gentleman's question showed that the number of offenders subject to the notification requirements and for whom the police did not have a current residential address has now reduced to 11. The offences for which these offenders had been convicted were as follows: three for rape; one attempted rape; two unlawful carnal knowledge; two indecent assault on a female; two making/possessing indecent images of children; one buggery. One person with a conviction for making/possessing indecent images of children was subject to probation supervision at the time they failed to comply with the notification requirements. Of the 11 offenders, four had been subject to a multi-agency risk assessment with no one being assessed as Category 3 High Risk i.e. someone whose sexual offending has been assessed as currently likely to lead them to seriously harm other people. PSNI pursue a policy of actively seeking to trace offenders who fail to comply with the notification requirements. This includes placing the offender's details on ViSOR and PNC to alert other UK police forces, checking with agencies such as social security to establish if the offender is claiming benefits etc, and providing full details to colleagues in An Garda Siochana who then complete similar checks for the offender in the Republic of Ireland.
