While officers weren’t stationed on the front door of Ross’s Hampstead property, a policing plan was drawn up ‘for the protection of the public’.
Reasons given for the outlay were potential dangers to the public from crowding of the pavement, spilling onto the road and impingement of traffic.
The Metropolitan Police said: ‘Local officers will continue to attend and interact at events of all kinds on their areas as part of their normal patrols as this is an integral way to foster support and trust in the police and to promote engagement and communication as we do for school fetes and the like.’
A police source told the Daily Mirror: ‘Most officers would rather spend time on proper jobs, rather than shepherding rubberneckers gawping at celebs in silly outfits.’
