In the United Kingdom, the Violent and Sex Offender Register (ViSOR) is a database of records of those required to register with the police under the Sexual Offences Act 2003 (the 2003 Act), those jailed for more than 12 months for violent offences, and those thought to be at risk of offending. In response to a Freedom of Information request in 2009, for example, Greater Manchester Police reported that of 16 people in their area placed on ViSOR since 2007 on their initiative and not as a result of a relevant conviction, four (25%) had clean criminal records.
