According to the BBC’s account, the examination concerns material linked to a number of detention operations conducted by British personnel between 2010 and 2013.
BBC News reports that evidence concerning the detention operations in Afghanistan has been referred to the police. The material is therefore under examination, but the source provided does not identify the police body handling it.
According to the BBC, the examination could expose British special forces to the risk of criminal proceedings. The wording indicates a possibility and does not confirm that charges have been brought.
The material provided does not establish which individuals are involved. Nor does it specify the alleged conduct, within the limits of the documentation available.
It also does not identify the police force that is examining the evidence. This detail cannot be inferred from the available headline and summary of the source.
In the material provided, the BBC does not establish that charges have already been brought or that criminal proceedings have begun. The outcome of the examination therefore remains undefined.
For now, the central point reported by BBC News is that the evidence has been passed to the police and is being examined, with the possibility of legal action against British special forces, without this amounting to confirmation of offences or indictments.
