A Hong Kong man jailed for killing his ex-wife with drain cleaner years ago jumped to his death on Thursday after allegedly attacking his new wife with a similar substance.

Wong Chi-sing, 67, was found severely injured on the ground near Hok Sam House on Lung Hang Estate in Sha Tin at about 9.40pm. He was taken to Prince of Wales Hospital, where he was confirmed dead.

Wong’s 40-year-old wife, who was from mainland China and had been married to him for about a year, was found near their home in the building with burns from the corrosive liquid.

She was taken to the same hospital, where she was said to be in a serious condition on Friday morning.

Police believed Wong, an air conditioning technician, had attacked his wife as they were having an argument at home, before jumping over corridor railings in their building. They found an empty bottle of cleaner, and an unused one, at the scene.

A police source said the couple had been having relationship problems, and the wife had wanted a divorce.

Wong, a former security guard, was jailed for eight years in November 2011 after being convicted of the manslaughter of his 40-year-old ex-wife, Song Ziqin, also a mainland native.

Song died a month after Wong poured two bottles of drain cleaner over her head in front of their nine-year-old daughter at their home in Pai Tau Village, Sha Tin, in June 2010.

The court heard they had clashed because of an extramarital affair.

Thursday’s attack was the second case of a similar nature in five days.

On Sunday, a 40-year-old woman working for Tsim Tung Ho Choi Seafood Restaurant at Empire Centre, Tsim Sha Tsui, was seriously injured after her husband attacked her there with corrosive drain cleaner.

Three other employees and two customers sustained minor injuries. The suspect was also injured.
