Commuters at a London Underground station were shocked to hear the sound of a couple making love broadcast over the tannoy.

Passengers at West Ham station in east London heard sounds of passion instead of the usual announcements about delays being relayed over platform loudspeakers during the rush hour.

A Transport for London spokesman blamed radio interference - but passengers were not convinced.

"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."

However, the Transport for London spokesman insisted: "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. It certainly wasn't coming from our staff."

He 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.
