Shocking CCTV footage has emerged of the moment a man was kicked through the top deck window of a London bus.
Video taken from behind the bus, by another double-decker, shows a man crashing though a pane of glass on the top-deck and falling into the road near Finsbury Park.
The footage was shown in a BBC programme, 'The Route Masters: Running London's Roads', which was broadcast on Sunday night. The programme charted how police investigate crimes on London's vast network of bus routes.
There were some 20,000 crimes reported on London’s buses in 2013 and Transport For London now funds a unit within the Metropolitan Police aimed specifically at reducing crime on public transport.
Detective Constable Tony Barun, a specialist safer transport command officer for the Met, told the programme: "It's still shocking. Although we see violence every day, it's our bread and butter, it's still shocking to see something as graphic and violent as this.
"We know these window can be kicked out with a great deal of effort, but to see someone kicked so hard that he actually goes through the window and it pops the window out of its frame - I've never seen that before."
A 38-year-old man was arrested five days later in connection with the incident but was later acquitted. The victim was left with severe injuries including, according to his sister, a broken back.
