A woman fell to her death from an upmarket hotel near Waterloo Station in central London.
Police, forensic officers and paramedics scrambled to the Park Plaza on the south side of Westminster Bridge.
A 45-year-old female was pronounced dead following the incident around 4pm on Monday.
Her death is not being treated as suspicious, the Metropolitan Police said.
Traffic built up in the area, which was cordoned off, while buses were forced to divert their normal routes.
Journalist Simon Bucks posted the photos of the incident on X, formerly Twitter, with the caption: “Massive police activity on the south side of London’s Westminster Bridge.”
