Mr Dizaei was cleared of perverting the course of justice in April

The lives of hundreds of black and Asian officers were being made "very, very miserable", he added.

And record numbers of officers were pursuing tribunal proceedings against the Met for racial discrimination.

Following the collapse of talks to reinstate Mr Dizaei, the National Black Police Association (NBPA) has called for a boycott of black and Asian recruits to London's police force.

Mr Dizaei, who is a legal advisor for the NBPA, told BBC News many recruits faced bullying and discrimination from their first day at Hendon police training college.

"I take hundreds of calls every week from black and Asian police officers and support staff who have had enough."

I am just absolutely amazed this can be done and the commissioner can sit back and allow so much collateral damage to be done to his force Ali Dizaei

Mr Dizaei, from Henley-on-Thames, Oxfordshire, told BBC News he was "very sad" and disappointed his reinstatement talks had collapsed.

He was suspended from his �52,000-a-year job in 2001 amid allegations of drug dealing and involvement with prostitutes.

Those claims never resulted in any charges against him, and despite a four-year investigation the high-ranking officer was cleared of dishonesty while charges of fiddling expenses were also dropped.

But since his suspension he had been paid to sit at home and do nothing, he told BBC News.

"This cannot be good for the Metropolitan Police and certainly it is not good for me and my family."

Mr Dizaei added: "�7m of taxpayers' hard-earned cash has been spent trying to put me behind bars for reasons best known to the handful of officers who embarked on this crusade.

Mileage claims

"Thankfully, 12 members of the jury, my peers, took less than two hours to find me, unanimously, not guilty.

"You put me before the highest court in the land, you put me before the highest judge in the land, over �200 worth of mileage claims, I was found not guilty.

"You would have thought that would be enough in this day and age. I have been vindicated.

"I fail to see why we have to spend another �1m on a potential disciplinary investigation then a further �1m on employment tribunal proceedings.

"I simply want to go back to work, do my job and put an end to this sad affair."

Mr Dizaei told BBC News he had been told he could return to work on the condition he would not be allowed to speak to any members of the public or supervise any officers or police civilian workers.

"How can a police superintendent go back to an organisation, put a plastic bag over his head, sit in a corner and do filing?

"It is nonsense - preposterous. No person of dignity would accept that.

'Collateral damage'

"I should be out there serving my community. I am being paid, I want to go out and do my job.

"There are 1,300 superintendents working in the British police service every day.

"They do not go into a corner not being able to speak to their public.

"I just want to be treated exactly the same. That is all."

"I do not want any more or any less."

Mr Dizaei told BBC News a "handful" of racist senior officers had set out to destroy his life and bully him "out of a job I love".

"That is repugnant."

"I am just absolutely amazed this can be done and the commissioner can sit back and allow so much collateral damage to be done to his force at the taxpayers' expense."
