In a week-long blitz, a total of 157 people were detained for various crimes, from illegal bookmaking to e-commerce offences.
The multi-agency anti-crime operation conducted from Aug 23 to 30 led to the arrests of some of the 128 men and 29 women picked up. The suspects are aged between 16 and 81.
The operation covered various locations in Jurong West, Tuas, Choa Chu Kang, Bukit Panjang and Bukit Batok, and was led by the Jurong Police Division. It was supported by officers from the Central Narcotics Bureau, Land Transport Authority and the Immigration and Checkpoints Authority.
In addition to those picked up, 310 people were also checked by the Singapore Police Force during the crackdown.
The Straits Times was present at a police bust on illegal horse-betting taking place at a Jurong West coffee shop on Aug 23, at around 2.30pm. Thirteen men and a woman between the ages of 53 and 72 were detained, with police seizing $4,421. The illegal activity took place in broad daylight and in full view of other coffee shop patrons and stallholders.
At the scene, the police seized bags of evidence including what looked to be numbered betting slips, newspapers containing details of horse races, and fat stacks of cash.
Assistant Commissioner of Police Devrajan Bala, commander of Jurong Police Division, said: "This joint operation led by Jurong Police Division is an ongoing enforcement effort to clamp down on criminal activities... The police will continue to work closely with other law enforcement agencies to take tough enforcement action against those who are involved in criminal activities."
The authorities gave a breakdown of those detained and the offences involved. In separate busts, 21 men and six women aged between 18 and 81 were picked up in connection with public gaming, vice-related activities, being suspected members of secret societies, and for traffic and vehicle-related offences.
