SINGAPORE - Four men have been arrested for allegedly circulating obscene materials in yet another Telegram chat group, the police said on Friday (Nov 8).

Aged between 26 and 45, the four men are involved in a chat group that alludes to a Hokkien vulgarity. The police were alerted to the chat group on Oct 24.

Three of the men have been established as the administrators of the chat group, based on preliminary investigations, while the fourth, a 26-year-old man, was found to have advertised the sale of obscene materials in the chat.

On Wednesday, when the four men were arrested, the police seized more than 15 electronic devices, including a central processing unit, several laptops, hard-disk drives and mobile phones.

In its statement, the police advised the public to stop joining such illegal chat groups.

"The police takes a serious view of anyone involved in criminal activities and will continue to take tough enforcement actions against those breaking the law," the police said.

This is the latest incident involving Telegram chat groups circulating obscene materials that the police are investigating.

In October, the police clamped down on a group called SG Nasi Lemak, which the police said was used by men to circulate obscene materials and promote vice activities. Four men, including two teenagers, were arrested for their involvement.

Another chat group, SharingIsCaring, is also being investigated by the police for sharing photographs of women and girls taken in public places, including in MRT trains.

Anyone found guilty of circulating obscene materials can be jailed up to three months, fined, or both.

The police are investigating the case.
