Investigation is in progress after pane of glass plummets 17 storeys from Old Broad Street office block

City workers in London had a lucky escape on Tuesday after a pane of glass fell 17 storeys from an office block building.

The 28-storey 125 Old Broad Street was only completed last year during an £80m refurbishment of the former Stock Exchange Tower. It was built by Bovis Land Lease and a new facade was designed by Grimshaw.

The 4m-wide panel of glass fell from a window and narrowly missed workers on their lunch break walking in the street below.

Surveyors from the City of London Corporation are examining the office block to learn more about why the panel fell. A spokesman for the City of London Corporation said: "The district surveyor is currently at the site investigating and the road was closed off by the City of London police."
