Ho Mei-yan wanted to take revenge on her husband because he cheated on her before she had an affair with chef Luk Chi-kan, the High Court was told.

Luk pleaded guilty yesterday to splashing corrosive liquid on Ho's husband on November 27, 2019, with intent to cause him grievous harm.

As Luk provided information that led to Ho's arrest and prosecution for instructing the attack, Judge Andrew Chan Hing-wai adjourned the hearing to October 4 to wait for details of Ho's case before sentencing Luk.

The defense said Luk committed the offense out of love as he was weak in dealing with matters of romance and hoped the court would consider a lenient sentence after he turned himself in and supplied the police with information.

Earlier, Chan heard Luk got to know Ho in 2018 while working in the same restaurant, and they became involved.

Ho told Luk that she wanted to take revenge on her husband as he had cheated on her and didn't pay the bills at home.

She instructed him to throw drain cleaner on her husband, the court was told.

After the husband parked his car at their Fu Ning Garden home in Tseung Kwan O, a man wearing a hat splashed corrosive liquid onto him as he walked out of the elevator, the prosecution said.

He felt severe pain on his head, face and body, and sought help at a nearby convenience store.

He was then rushed to Tseung Kwan O Hospital.

Two days after the incident took place, Luk turned himself in at the Wong Tai Sin police station and admitted to throwing the drain cleaner.

He said he threw a cup of corrosive acid on Ho's husband before escaping in a taxi to have a drink with his friends.

The husband suffered a third-degree burn on 3 percent of the skin on his head, neck and upper torso.

He also suffered injuries to his eyes. He was discharged from the hospital after three weeks.
