Ng often cursed at victim and challenged him to fights
The worker, 34-year-old Jahidul, worked for Ng at his plumbing company, HYL Enterprises, and lived in the same house in a room where tools were kept.
According to court docyments, Jahidul said Ng, now 59, would often enter his room at night, turn on the lights and scold him with vulgarities while pointing a finger at his nose.
Ng would also challenge him to fights, but he would not dare to answer as he was frightened of Ng.
Unable to take the abuse, Jahidul requested several times for Ng to send him back to Bangladesh, but Ng had purportedly refused to do so.
