style="text-transform: uppercase;">Kuala Lumpur: The hitman who pulled the trigger on Datin Wong Siu Ling in the Taman OUG shooting was not paid the RM10,000 he was promised by his hirer, a police source said. The 29-year-old factory worker arrested in Tampoi Utama, Johor Baru, on Saturday morning was the ninth suspect detained in connection with the high-profile street murder on July 6.

"The suspect admitted to police he was the pillion rider who shot Wong," the source said.

"He also admitted he was given the gun by one of his accomplices at his home the night before the incident."

Inspector-General of Police Tan Sri Khalid Abu Bakar confirmed the suspect was the shooter.

"We are still looking for more suspects who we believe have fled the country," he said.

Last week, police said a RM13 million ceramic business deal that went sour was believed to have set off Wong's murder.

The 32-year-old had given the money last year to a businessman, who went into hiding soon after that.

She persisted in asking for the return of her money after she realised the venture was going nowhere.

Police had said Wong had hired a private investigator to track down the businessman earlier this year and this could have led to her murder.

She had obtained the investment capital from her husband, Datuk Wong Chun Kee, who had business dealings in China.

Police were also investigating how he had made the money and the possibility of money laundering.

On July 19, police detained eight people, including the businessman, who was the alleged mastermind, and his wife, believed to have played the role of middleman in hiring Wong's killers.

Among the others arrested were a man and his wife who ran a restaurant. Other suspects held include the hired killers picked up in Chemor, Perak, and two accomplices. They are thought to have been paid about RM60,000 for the execution.

All were aged between 26 and 54. A Glock 19 recovered from the hired killers' car is believed to have been used in three other shooting incidents in 2013 and last year.

The incidents involved a murder, an attempted murder, and a case of discharging a firearm towards a victim's house.

All the cases took place in Sungai Siput Utara, Perak, and were related to drug activities.

Police confirmed the cases based on the bullet casings obtained from the scene of Wong's shooting and the gun seized.

However, they are still investigating if the same hired killers were involved.

The murder fuelled speculation that Wong's husband was being hounded by investors in a Ponzi scheme in China.
