Ten Metropolitan Police officers based at Charing Cross Police Station are facing accelerated misconduct hearing after an undercover TV documentary.
Some called for immigrants to be shot, revelled in the use of force and were dismissive of rape claims in the BBC Panorama.
Reporter Rory Bibb, who got a job in the central London custody suite, spent seven months filming covertly up to January this year.
The Independent Office for Police Conduct says three police sergeants, five police constables, a former Met PC and a Gloucestershire officer who transferred from the Met are said to have breached standards of professional behaviour and will be before panels “in the coming weeks”.
Last Thursday, a sergeant was arrested on suspicion of perverting the course of justice relating to an incident that took place at Charing Cross on October 2 - the day after the show aired.
Commissioner Sir Mark Rowley said: “I have been very clear from the outset that I wanted to see all those responsible for this appalling behaviour facing gross misconduct hearings at the earliest opportunity. They have no place in the Met.
“After watching Panorama last week and seeing the behaviour for myself, I requested the early consideration of accelerated misconduct hearings, and I welcome the IOPC’s decision to pursue this course of action.
“We have worked together to deliver this uncompromising approach at greater speed than ever before and the hearings will take place by the end of the month.
“Londoners would expect nothing less and for those found responsible to be exited from the Met and off the payroll as soon as possible.
“Within 48 hours of the allegations being received from Panorama, nine officers and one staff member had been suspended, with two more officers removed from frontline duties. I am extremely grateful for the swift enquiries undertaken by the IOPC since the investigation was referred to them.
“We have since disbanded the custody team at Charing Cross, made changes to local leadership and have begun wider work to identify any other areas of concern in detention teams across the Met. More action will follow.
“This comes in the context of the biggest corruption clear-out in British policing history, which has seen more than 1,400 officers and staff leave the Met in the last three years.
“Much more work will be required to redress the systemic, cultural, leadership and regulatory failings that have allowed misogyny, racism, anti-Muslim hate and a lack of public service ethos to put down deep roots.
“While there are no quick fixes, I will be relentless in working with the good majority of our people to bring this about.”
IOPC Director General Rachel Watson said: “We were appalled by some of the behaviour and conduct displayed by a group of Met officers based at Charing Cross in the documentary.
“The public would rightly expect swift action being taken to remove officers who have no place in policing and a large team of investigators from across the country have been working at pace to analyse the evidence.
“As a result, we have this week notified the Met and Gloucestershire Police of our view that there is sufficient evidence to merit bringing accelerated gross misconduct proceedings for 10 officers.
“This sends a clear message that the type of behaviour seen in the documentary is taken extremely seriously and immediate action will be taken to enable the forces to dismiss officers at the earliest opportunity, where appropriate. We also acknowledge the swift assistance of officers from the Met’s Directorate of Professional Standards and the evidence they’ve provided to support our investigation.
“We anticipate that both forces will agree with our decision on accelerated proceedings and make arrangements for these hearings to take place as soon as possible in the coming weeks, in line with proper processes.”
