St Paul's underground station in the London's financial district was closed as police responded to a security alert in the area. Reuters have reported that the item being investigated in the area has now been deemed non-suspicious, and roads have started to reopen.

A spokesman for City of London Police told media on Tuesday that they were "in attendance in St Martin's Le Grand (EC1) following a report of a suspicious package inside a building. Called at 10.23am."

The street was cordoned off and people were advised to avoid the surrounding area. Some shops and businesses were reportedly evacuated.

Nearby office workers said were told to keep away from windows and stay inside, others shared pictures of colleagues gathered on stairwells as emergency procedures were implemented.

Always nice when the police close all the roads surrounding your office and have the sniffer dogs out ... 😳 #lunchinsidetoday #stpauls A post shared by George (@georgeburgess1) on Dec 5, 2017 at 2:50am PST
