Just before rush hour yesterday, part of a building in the Aldwych area of central London collapsed, leaving one person injured and 200 more evacuated.
Firefighters were called at around 4:14pm after part of the building and the scaffolding around collapsed.
Construction workers were among the people fleeing the collapse after they heard a loud noise as walls of the six-storey building caved in, leaving debris and smashed cars in the street below.
Roads around the hazardous area have been cordoned off and closed to allow police and fire brigade to carry out investigations and make the area safe.
One man is now in hospital after suffering head injuries while 100 made a lucky escape from the building. 100 more people were also evacuated from neighbouring buildings, including the London School of Economics Library, as a precautionary measure.
