A man has been banned from having sex unless he lets police know at least one day in advance.

North Yorkshire Police have sought a "sexual risk order" for the man who has not yet been convicted of a sexual offence, but who is thought to be unsafe for the public, according to the York Press.

The man from York must contact the police to tell them of any woman he plans to have a relationship or one-night stand with.

Sexual risk orders can be made by a court on an individual "who has done an act of a sexual nature and who, as a result, poses a risk of harm to the public in the UK or children or vulnerable adults abroad."

It says that "the individual does not need to have committed a relevant (or any offence)" for the order to be imposed.

A full sexual risk order lasts for a minimum of two years, and breaching one can lead to a prison sentence of up to five years, despite no initial sexual offence conviction.

Sarah Green, acting director at End Violence Against Women, said such orders were necessary to keep potential victims safe.

"We have crisis levels of rape and sexual assault in this country for which it is often very difficult to get justice.

"We know from research that these offences are commonly repeat offences and these orders are a tool for protection of the public."
