A couple was recorded on camera engaging in a sexual act at the void deck of Block 666 Yishun Avenue 4 today (Sep 17) at around 4am.

Stomper Ro was dropping a passenger in the area and came across what happened.

In a video he sent, the man can be seen seated down as the sexual act was being performed. His female companion had taken off her top and underwear.

A second video shows the man standing up with his shirt and pants removed as the duo continued on with the lewd activity.

Around two minutes after the Stomper arrived at the HDB block, both of them put their clothes back on and left.

Ro said in a telephone interview that the couple looked to be in their early 20s.

He felt that their actions were inappropriate

Even though it was very early in the morning, they were still in full view of the public.

"This type of thing shouldn't do. Terrible, this one," he expressed.

Stomp will not be uploading the videos due to their graphic nature.
