Seconds later, as the alarm is set off, he can be seen climbing back out of the hole in the roof after failing to get the vehicle started.

Police hunting the would-be thief have appealed for witnesses to the attempted robbery at 7.45am on 29 September in Mill Street, in London’s wealthy Mayfair, to come forward and help them with their investigation.
