The operations took place between 24 April and 6 June, with the Criminal Investigation Department and seven police land divisions arresting 147 men and 11 women, aged between 36 and 83, for allegedly engaging in illegal activity.
During the operation, police seized close to six figures in cash, several mobile phones and what authorities believe to be documented betting records.
Police investigated multiple locations, including Telok Blangah Crescent, Bukit Merah View, Serangoon Central, Bedok, Bukit Batok, Woodlands, Marsiling and Yishun.
The investigation is still ongoing, but if found guilty, the perpetrators can be fined, jailed or both, depending on the severity of the illegal activity, reports CNA.
"Members of the public are advised to steer clear of all forms of illegal gambling activities and to take the prevailing safe distancing measures seriously," said the police.
Illegal gambling is a serious offence in Singapore. Back in May, police arrested 17 people for gambling inside a residential unit and disregarding social distancing measures. Authorities seized gambling-related paraphernalia and the suspected instigator, a 62-year-old man, might be facing a fine of SGD50,000 (US$37,783) and three years of jail time.
People disregarding social distancing measures can also be fined up to SGD10,000 or jailed up to six months.
The Ministry of Sustainability and the Environment recorded more than 600 fines that were issued to individuals who breached the safe distancing measures in this year alone.
A common type of breach is large social gatherings, as Singapore doesn’t allow gatherings of more than two people until 13 June.
