Parents appeal in Chinese murder

Version 0 of 1.

The families of two Chinese students murdered in Newcastle are appealing for help to catch their killer.

The mutilated bodies of Zhen Xing Yang and girlfriend Xi Zhou, both 25, were found in their flat on 9 August.

No arrests have yet been made despite appeals to the English and Chinese communities on Tyneside and in London.

Family members of both students have flown to Newcastle from China and will make an appeal for information at a news conference on Thursday.

A reconstruction of the last known movements of Zhen Xing Yang and Xi Zhou has featured on the BBC's Crimewatch.

Callers to the programme suggested a name for a lodger who police are trying to trace.

Mr Zhen had been tortured before being stabbed to death. The couple's cat was also drowned by their killers.
