A convicted loan shark who was accused of being involved in a 100 million yuan (US$ 14.5 million) investment scam is believed to have committed suicide five hours after he was released on HK$1 million (US$127,392) bail.

Sunny Wong, formerly known as Wong Kwai-fun, 62, fell from the eighth floor of a multi-story car park in Yau Ma Tei, Kowloon at 10:30 pm on Wednesday. He was pronounced dead at Kwong Wah Hospital, Apple Daily reported.

Four suicide notes were found in his car, revealing that he felt “sorry for his family and hopeless about the future.”

Police found nothing suspicious about what they are treating as a suicide.

It was understood that Wong had just met with a friend in the car park. After asking the friend to go to a convenience store to buy something, Wong jumped to his death.

Wong was charged with one count of conspiracy to defraud following his arrest on Monday. He appeared in West Kowloon Magistrates’ Court and was released on HK$1 million bail on Wednesday afternoon.

On Thursday afternoon, one of Wong’s brothers, Wong Kwai-wing, 60, turned himself in at Mong Kong Police Station and is being detained on suspicion of conspiracy to defraud and false imprisonment.

The brothers were alleged to be the masterminds of a case in which a Hong Kong businessman was held hostage at a hotel in Shenzhen, China for three days in February. They allegedly cheated the victim out of about HK$1 million and demanded a further HK$290 million in ransom, Sing Tao Daily reported.

The Wong family, comprising four brothers and two sisters, are notorious for a variety of crimes, including massive loan-sharking operations and threatening top government officials over the past 30 years.

The deceased Wong, the eldest brother of the family, was jailed for 10 years in 1987 for his involvement in the murder of a businessman and various offences related to loan-sharking.

Wong was released in 1999 and has kept a low profile but continued to operate finance companies and property businesses. He lived with nine children in a luxury house in Kowloon Tong.
