A British man who handed himself in to Chinese authorities has been charged with a series of child sex offences dating back up to 15 years. Neil Robinson, 47, from Staines, Surrey, was detained by officers after arriving at Heathrow Airport on Friday, Surrey Police said. He was taken into Staines police station and later charged with six counts of unlawful sexual intercourse with a girl under 13, one charge of taking an "indecent photograph/pseuo-photograph of a child" and one charge of encouraging prostitution of a girl under 16. A police spokesman said the alleged offences took place between 1998 and 2002, and Robinson will appear at South East Surrey Magistrates' Court later. Detective Inspector Becky Molyneux, of the Staines Public Protection Unit, said: "Mr Robinson's return to the UK is the result of weeks of hard work from a number of agencies and co-operation from the Chinese authorities; to whom we are extremely grateful."
