SINGAPORE - A couple allegedly stripped and had sex in a jacuzzi at Resorts World Sentosa's Beach Villas last Friday afternoon, in full view of horrified guests.

While the jacuzzi was meant only for the couple's villa, it sat within a larger pool being enjoyed by other guests.

One guest, who wanted to be known only as Madam Lee, told The Sunday Times that she was alerted to the incident when her two children and their two cousins - aged between five and 11 years - noticed that the woman was not wearing anything from waist down. The children were swimming in the pool at the time.

The 41-year-old housewife, who was there with other family members after one of them paid about $1,000 a night for their villa, said she alerted the concierge immediately, and told the children not to look.

"But the couple started having sex in the jacuzzi. It was very obvious, and my mother shouted at them. I quickly ran in to get my phone and snap pictures, and they stopped only when they saw me doing that," said Madam Lee.

"I would have closed one eye if the kids were not there, but I'm surprised the couple did it even though they were aware there were children around."

When contacted, a Resorts World Sentosa spokesman said it is investigating the matter.

Those guilty of public nudity can be charged under the Miscellaneous Offences (Public Order and Nuisance) Act, and face up to three months in jail, and a fine of up to $2,000. For committing an obscene act in public, the maximum punishment is three months in jail and a fine.
