Investigation Over Facebook Group
An investigation's looking into whether Met Police officers used a closed Facebook group to discuss racist views.
A Metropolitan Police spokesman said "concerns" were raised about comments made on a Facebook group with the Directorate of Professional Standards (DPS) in April.
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.
The spokesman said: "The group administrators have set the privacy settings for the group as "secret" but we understand it to include former and serving MPS officers among its members.
"DPS is assessing the information it has received to determine whether any serving MPS officer or staff may have committed any acts of misconduct and will also look to see if any criminal offences may have been committed. Should either be disclosed they will be fully investigated."
