The son of a Chinese government official was charged at the weekend for drugging and sexually assaulting a woman in Britain in late 2011. Zhong Xuanyu, 25, was found guilty of sexual assault and handed a six-year prison sentence by Newcastle Crown Court, London-based newspaper the Daily Mail reported on its website on Monday. Zhong, a student at Northumbria University in Newscastle upon Tyne in North East England, had allegedly watched hours of date-rape pornography online and fantasised about copying what he saw. In December 2011, Zhong offered a woman a drink spiked with drugs he had bought online and then "forced himself on top of her" while she was in a drugged state, the court said, adding that he had intended to rape her but then "changed his mind". He was arrested after the victim recalled certain parts of the ordeal and reported it to the police, the MailOnline report said. Police found eight downloaded pornographic videos on Zhong’s personal computer, which had been viewed on different occasions since November 2011. He was also said to have carried out “specific searches” on different types of date-rape drugs. Two types of drugs that he bought online had failed to work, the report said. Judge Paul Sloan QC said: “The videos showed women apparently being drugged and then, while incapacitated … sexually abused and raped by a number of males. You accepted when pressed during the course of your evidence that you were sexually excited by such videos.” Sloan added: “This was a premeditated offence. You offered your victim a drink and, when she accepted, you laced that drink with the drugs you obtained. Her recollection of events thereafter is very limited.” The court also heard that Zhong’s father had “tracked the victim down” and threatened her in an attempt to prevent her from giving evidence. Sloan said the case had been reported to mainland authorities. A spokeswoman from Northumbria University said the school was aware of the situation but could not provide further information at present.
