A 28-year-old Hong Kong man was sentenced to 18 years in jail at the High Court on Monday for raping and torturing two victims he lured to his home through social media.

Cheung Tze-hong, an unemployed drug addict, earlier pleaded guilty to four counts of rape and one count each of false imprisonment, robbery, indecent assault and assault occasioning actual bodily harm, Apple Daily reported.

The court heard that a psychologist who examined Cheung described him as an “immature, carefree and self-centred” person of a sexually promiscuous inclination, adding that he was likely to re-offend.

The case came to light after a 28-year-old woman identified as Y was contacted by Cheung via Facebook on December 14, 2016. Cheung later lured Y to his home in Tuen Mun in the New Territories and detained her for four days.

Cheung restrained Y with cable ties and raped her three times; he also threatened her with a knife and heated up the knife blade with a lighter and scorched Y’s thighs.

Cheung was also accused of raping a 22-year-old woman, identified as X, four days before he assaulted Y.

X went to Cheung’s flat on December 10, 2016, after he lured her with an offer of several hundred Hong Kong dollars to keep an eye on a store he claimed to be running.

But when she arrived at the flat, Cheung tied X’s neck and hands with cable ties before raping her.

Justice Judianna Barnes Wai-ling commented that this was an appalling case, as the defendant lured the two victims to his home, threatened them with physical and verbal violence and raped them.

Citing Cheung’s use of violence and his failure to wear a condom during the rapes as aggravating factors, the judge sentenced Cheung to 18 years’ imprisonment.
