London, Nov 7 Brit commuters at West Ham station were shocked when they heard loud groans of a couple having sexual intercourse being broadcast over the tannoy.

Passengers at the station in east London heard the lovemaking antics being relayed over platform loudspeakers during the evening rush hour on November 5.

"The noises heard by passengers were not from within our station. We believe they were a result of some sort of interference with our public address system," the Telegraph quoted a spokesman for Transport for London as saying.

"It certainly wasn't coming from our staff," he stated. e said the station's public address system worked on radio waves and somebody must have been broadcasting on the same wavelength. He said staff had turned off the loudspeakers as soon as they realised what was going on.

But passengers had different interpretations.

"It was definitely a couple doing it there and then," Laura O'Connor told the London Evening Standard newspaper.

"He was grunting loudly and she sounded like she was having a great time. The driver must have heard it, too, as the doors stayed open longer than usual," she added. (ANI)
