A man has died after plunging nearly 100ft from a sixth floor balcony bar at the Tate Modern gallery in London, the police have confirmed.

The incident was witnessed by hundreds of tourists, many of whom were sunbathing outside the iconic building.

The man, whose identity has not yet been confirmed, fell from the members' bar balcony around 6pm on Tuesday evening.

The sixth floor bar overlooks the building’s main entrance.

Onlookers were stunned by the incident, with one tweeting that "Seeing the guy who had committed suicide and jumped off the Tate modern has been the most traumatic thing I have seen".

London Metropolitan Police said the incident was reported at 5.55pm, a very busy time of day for the Tate Modern, and a London Ambulance attended.

The man, who the police say was in his 40s, was pronounced dead at the scene.

Officers said they know the identity of the man, whose next of kin have been informed, but are awaiting official confirmation.

His death is being treated as non-suspicious, and a post-mortem examination and inquest will follow.
