A formal complaint has been received which is being investigated by the DPS (Directorate for Professional Standards) and we appreciate the concerns that have been raised.
The DPS inquiry is taking place in conjunction with Operation Herne's investigation into the wider issue of past arrangements for undercover identities used by SDS officers.
We can confirm that the practice referred to in the complaint is not something that would currently be authorised in the MPS (Metropolitan Police Service).
