They faced angry Tottenham residents in the first episode and will be seen dealing with crowds at the Notting Hill carnival in the next.

But we have yet to see the police officers starring in a BBC fly-on-the-wall documentary, The Met, come to face-to -ace with perhaps their most formidable crowd yet – the residents and crime campaigners of Hampstead.

A heated public meeting, called by Hampstead residents to raise their concerns about policing in the area, with borough commander Richard Tucker and other officers, is to feature in the third episode of the series.

The documentary film crew filmed the meeting in St Stephen’s, in Rosslyn Hill, on October 12, which was called following a spate of “ultra violent” robberies by hammer-wielding thugs on mopeds.

The meeting began with crime victims and local residents serving up a litany of accusations about Camden officers mishandling cases.

As the Ham&High reported at the time, Det Supt Tucker heard a string of complaints, including detectives failing to recover CCTV recordings or speak to witnesses, and railed against general poor communication with victims.

He responded: “As a detective I sit here and I cringe when I hear some of the stories you say. I can’t understand someone who goes into public service, because that’s what the police is, and doesn’t serve the public.”

Frognal and Fitzjohns Safer Neighbourhoods Panel chairman Jessica Learmond-Criqui, who organised the meeting, has not previewed the documentary footage but said: “We are very much looking forward to watching it!”

Episode three of The Met will be aired on BBC One on June 22.
