An investigation has been launched into claims that Metropolitan Police officers used a secret online forum to air racist views about ethnic groups.
Scotland Yard said 'concerns' had been raised about a Facebook group amid allegations serving officers had posted offensive comments about gipsies and travellers.
Its internal watchdog, the Directorate of Professional Standards, has been investigating the matter since April, it has been revealed.

Representatives of the traveller community contacted police in June about the same Facebook group and these complaints were being 'looked at in detail as part of the DPS assessment', according to the spokesman.
Some of the comments were made during a discussion in March about the BBC Trust's decision to clear Jeremy Clarkson and other Top Gear presenters of wrongdoing for their use of the word 'pikey', a derogatory term for travellers, according to The Independent on Sunday.
