Hundreds Evacuated From Shard After Fire Alert
About 900 people have been evacuated from London skyscraper The Shard after smoke was discovered in the basement.
Firefighters are now investigating what caused the smoke at the 1,004ft-high building - the tallest in Western Europe.
Seven fire engines and 50 firefighters were at the scene near London Bridge following reports of a blaze.
A fire alarm had gone off, leading to the mass evacuation and a 50-metre cordon was put in place.
No injuries have been reported and a spokesman for The Shard said there had not been a fire.
Meanwhile, Sam Bradley, who works for the Foresight Group on the 17th floor, said workers were told to evacuate the building by a message over the tannoy system.
He told Sky News: "It was all really well organised. We had four or five marshals who made sure everyone was calmly removed from the building.
"We have been told and trained how to get out of the building and so everyone was very calm.
"Everyone knew what was going on and what to do."
Carolynne Croucher said she was told by the police that the road would be closed for a while.
She added: "They (police) wouldn't let anyone through. The shops were shut and the fire engine had rolled out the hose.
"And they were pulling up the drain paving slabs and looking then putting them back."
A tweet from @TheShardLondon said: "Emergency services are responding to a fire alarm at The Shard. Evacuation procedures have been followed and we are ready to assist as needed."
The London Fire Brigade said there was no evidence of a fire in the building.
A fire brigade spokesman said: "Seven fire engines remain at the Shard as crews continue to investigate what caused the smoke in the basement. A 50M cordon's in place."
In a statement the Metropolitan Police said officers were contacted at 11.09am after London Fire Brigade were called to reports of a fire at the premises.
Designed by Italian architect Renzo Piano, the 87-storey skyscraper was begun in 2009 and completed in 2012.
It replaced the Commerzbank Tower in Frankfurt as the tallest building in the EU and replaced Canary Wharf as the tallest in the UK.
