Work on the Olympic Stadium has been stopped following a death of a construction worker.
The 44-year-old man was found dead following an apparent fall from the East London venue.
The Metropolitan Police confirmed in a statement: "Officers were called to the stadium at 07:30 this morning, Sunday, 28 June, to reports of a person having fallen from the stadium to the ground and being unconscious.
"The man was unresponsive when officers arrived at the scene. The London Ambulance Service attended and the man was pronounced dead shortly before 08:00.
“Formal identification has not yet taken place. However, officers are confident that they know the identity of the deceased."
David Goldstone, chief executive of the London Legacy Development Corporation, said: "As yet the exact cause of death is unexplained, but we have stopped all work on site and will cooperate fully with the emergency services and all other relevant authorities on their investigations.
“We will also be conducting our own thorough examination of events."
The stadium is currently being transformed into a venue for the 2015 Rugby World Cup later this year before becoming the permanent home of West Ham from 2016.
