Hong Kong police were on Monday hunting the stepson of a woman who died after she was attacked with an electric saw and a knife near her home.

A source said the stepson, aged in his 40s, who has fled the city, was being sought after the brutal killing of Lau Hung-lee, 54, on Kam Pok Road in Yuen Long in the New Territories on Saturday night.

Acting superintendent Tai Yuk-lun of the Yuen Long district crime squad said the victim had suffered “multiple cut wounds to the neck and wrists and multiple stab wounds to the abdomen and chest”.
