Amandeep Kaur Grewal, who is of Indian origin, was singled out for unfair criticism and treatment by trainer Pc Lucinda Rigby because of her race at the Metropolitan Police's training school in Hendon.
When Mrs Grewal complained, Pc Rigby told her other students were laughing at her behind her back.Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/sikh-news/26000-sikh-recruit-wins-payout-humiliation-police.html
Mrs Grewal, 38, told how some of her fellow recruits treated her in a "less than friendly fashion".
Reading employment tribunal heard how another trainer had to hold a diversity class to deal with animosity towards Mrs Grewal.
The panel rejected the Met's claim that trainers had considered her skills poor. It found she had been unfairly targeted and said Pc Rigby's remark about colleagues making fun of her "inappropriate" and "hurtful".
It found the Met guilty of race and religious discrimination. Mrs Grewal, of Teddington, now a serving Pc at Kingston police station, is set to be awarded a payout for hurt feelings.
She is married to a police officer and attended the Hendon training college in November 2007. She also told how Pc Rigby singled her out for "excessive supervision" during her officer safety training. She said her application of handcuffs was checked more often than for other students.
The Met claimed this was "mere chance" and that trainers did not think Mrs Grewal was up to scratch. But in its judgment, the tribunal ruled: "If this were truly the case, we would have expected to have seen particular remedial steps put in place. They were not." After Mrs Grewal complained to Met chiefs, she had a meeting with Pc Rigby in March last year. The panel ruled: "Pc Rigby told Mrs Grewal that other students had been laughing at her. This was an inappropriate and potentially undermining comment.
"Pc Rigby acted in this way because she felt defensive about allegations of race and religious discrimination."
Mrs Grewal failed in her claims of racial and religious harassment. Pc Rigby's mistreatment was distressing but not sufficiently serious to amount to harassment, the panel ruled.
Mrs Grewal's solicitor Jag Brar, of law firm Richmond and Barnes, said: "This case was particularly disturbing because it related to allegations of discrimination during police training. No recruit should have to go through the anguish Mrs Grewal suffered."
A Scotland Yard spokesman said: "The Metropolitan Police Service will give full and careful consideration to the decision. Pc Grewal remains a valued member of the force."
