However, a jury found him guilty of murdering Sze Ming-lan, 35, Sun Xiumin, 30, and Tse Hau-yuen, 35, at their one-woman brothels in March 2008.

Justice Clare-Marie Beeson told him: 'By your wicked crime, you've deprived (the victims) of their lives and destroyed their families.'

Police traced Razaq through a palm print, blood and semen stains at the crime scenes.

Police Detective Senior Inspector Lui Tak-keung said there was no evidence to support Razaq's claim that he was acting under orders from Macau debt collectors.
