FOUR people who drowned an alleged triad boss in a basin of water were found guilty of manslaughter by a High Court jury yesterday.
They were also convicted of forcible detention.
The jury, however, returned a ''not guilty'' verdict on the three men and a woman accused of murdering Tong Yim-tsan, 41.
Printing artist Leung Siu-hong, 23, his 24-year-old lover, Wong Pui-ling, and cleaning worker Chan Chi-ho, 26, were found guilty of forcibly detaining Tong for a $2 million ransom. Lee Kwok-wah, 18, was found guilty of false imprisonment.
Justice Stock deferred sentencing to May 7.
The court heard during the trial the alleged ''big brother'' owned part of a Wan Chai karaoke lounge where Leung and his lover were employed but they resigned after Leung had a row with Tong over Wong.
