POLICE officers did “absolutely nothing wrong” when stopping a car in which Labour MP Dawn Butler was a passenger, according to the Metropolitan Police Federation chairman.

Ken Marsh urged bosses at the force to release body-worn camera footage from the officers involved, insisting: “We’ve got nothing to hide.”

The federation represents thousands of rank and file officers in the London area.

Butler accused police of racial profiling after the BMW she was travelling in was pulled over in Hackney, east London.

The car was driven by a friend, who is also black.

Butler, the MP for Brent Central, filmed the incident.

Scotland Yard said the stop was a result of an officer having “incorrectly entered” the car’s registration plate into a computer to wrongly identify it as a vehicle registered to Yorkshire, but did not explain why the search was carried out in the first place.

The MP for Brent Central, in north-west London, said in an interview with the PA news agency: “It’s obviously racial profiling.

“We know that the police is institutionally racist and what we have to do is weed that out. We have to stop seeing black with crime. We have to stop associating being black and driving a nice car with crime.”

Her footage of the stop showed an officer saying police were carrying out searches because of “gang and knife crime”.

Butler told the officers: “It is really quite irritating. It’s like you cannot drive around and enjoy a Sunday afternoon whilst black, because you’re going to be stopped by police.”

Marsh said: “We are fed up with individuals being allowed to film my colleagues with impunity and put it out on every social media strand within five seconds, wherever they want, but we’re not allowed under legal grounds … to do the same, to put my colleagues’ body-worn camera out immediately.

“Now, that sounds a bit perverse, don’t you think, because we’ve got nothing to hide.

“I’m talking about transparency here.

“I, as the chair of 30,000 officers, am saying: put it out there.

“We have no issues because all the time you will see by watching it that the officers have done absolutely nothing wrong.

“If you think they’re that stupid in this day and age that they would act in an inappropriate or unlawful way knowing they’re filming themselves, I mean, come on, let’s have some logic.”

Marsh said it was “very, very frustrating” for officers that they could not release footage they have filmed when responding to incidents.

He added: “They go back and view it themselves straight away.”

Marsh went on: “I can assure you, my colleagues have done absolutely nothing wrong other than act professionally and appropriately without fear or favour.

“We are being tried by media just to the point that every cop now just apologises before they do anything.

“This is absurd.

“And it’ll get to the point that they’ll stop doing it and then you know what will happen.”

Asked what will happen, Marsh replied: “Crime will go through the roof, deaths will go through the roof, people will carry knives with impunity, you’ll go back to the Theresa May stop-and-search scenario.

“I think you’ll find deaths went up in London 71% after that and they were begging us to do stop and search.”

Marsh said talks have been held with deputy commissioner Sir Steve House about releasing the footage, adding: “He’s assured me they’re looking in to it.

“It’s legal process.”

The Independent Office for Police Conduct launched an investigation into whether officers in England and Wales racially discriminate against ethnic minority people.

The latest official statistics for stop and search showed a disparity rate of 4.3 for all black, Asian and minority ethnic people and 9.7 for black people.
