Serdang police chief A Anbalagan said that in the 9pm raid, nine individuals were arrested including three minors and a Chinese national whose visa has expired.

He said the syndicate promoted gambling through the Line application and several websites by offering bets ranging from RM50 to RM10,000 with profits reaching RM100,000 a day.

“Preliminary investigations found that the suspects aged between 16 and 29 were paid RM3,000 to RM3,500 a month and they were recruited through social media,” he said at a press conference at the Serdang district police headquarters here today.

He said the three teenagers, comprising a female and two male suspects, were released today on police bail while the rest have been remanded for six days until Sunday.

Anbalagan said a check found that two suspects had previous criminal records including for drug-related offences.

In a separate development, four men including two Indonesians aged between 20 and 30 were arrested in two raids in Petaling Jaya last Sunday after being suspected of being involved in six robbery cases involving 24-hour stores around Serdang, Petaling Jaya and Kuala Lumpur.

Anbalagan said all those arrested were members of the “Geng Apoi” believed to be active in robbery activities for the past six months.

“Their modus operandi is to pretend to be customers and when they sense the opportunity, they will rob in a group,” he said.
