Melbourne, Nov 24 A young couple was caught having sex in full view of passers-by at the top of Sydney's historic clock tower.

From pictures obtained, the couple could be seen naked as they engaged in sexual activities against the balcony underneath the giant clock across the road from Broadway Shopping Centre, near the University of Sydney.

They were in full view of the busy street below and seemed to be putting themselves deliberately on display, and soon there was a big crowd of onlookers ogling up at them.

The incident took place on November 20, and a bystander had taken the pictures from a bus stop across the road, where people were pointing and laughing at the twosome.

"A few other people had noticed as well and when I started taking photos everyone in the area started to look up and point, laugh, grin," the Daily Telegraph quoted the witness as saying.

"From the looks of it, the couple did seem to know they could be seen and seemed complete unfazed," the witness added. (ANI)
