London's About Us light show at the Tower of London on Saturday 19 November was marred by overcrowding and poor layout, according to an attendee.

Despite being what the filmer called "a great show" things became chaotic thanks to overcrowding, made worse by a layout that funnelled people into the event via a narrow bit of pavement.

The filmer reported that people took over 15 minutes to get to the nearby Tower Hill station when the show finished.

The station was then closed for a period due to a dangerous build up of passengers.

It was also announced that one of the About Us light shows would be canceled.
