Members of a jury in the trial of a businessman accused of murdering a Manchester Metropolitan University lecturer and his family in their home wept as a harrowing 999 call was played in court.
Anxiang Du, 54, is accused of stabbing to death lecturer Jifeng "Jeff'" Ding, his wife, Ge "Helen" Chui, and their two daughters, Xing "Nancy" 18, and Alice, 12, on April 29, 2011.
Du has denied carrying out the four murders on the day of the royal wedding between Prince William and Kate Middleton.
Prosecutors allege Du stabbed the Ding family in order to "avenge himself" after their business relationship turned sour and he ended up owning thousands of pounds in costs following a lengthy legal battle.
