Comments about the Hillsborough disaster made by a chief constable in an email will be investigated by another police force, it has been confirmed.
South Yorkshire PCC Shaun Wright said he has received a complaint regarding the content of emails sent by South Yorkshire Police chief David Crompton.
Mr Crompton sent an message to his senior staff last year which appeared to suggest a campaign group representing families of those who died was not telling the full truth about the 1989 tragedy.
The email read: "One thing is certain - the Hillsborough Campaign for Justice will be doing their version ... in fact their version of certain events has become 'the truth' even though it isn't!!
"I just have the feeling that the media 'machine' favours the families and not us, so we need to be a bit more innovative in our response to have a fighting chance otherwise we will just be roadkill."
Mr Wright said the chief constable of Cambridgeshire, Simon Parr , will now investigate. Mr Crompton said today he had thought the matter was "completely closed" after he apologised earlier this year.
The PCC said today: "I have today recorded a complaint against the chief constable of South Yorkshire Police, David Crompton, in relation to internal emails concerning the Hillsborough tragedy and its aftermath.
"The request has been submitted by a firm of solicitors in Liverpool acting on behalf of a number of individuals affected by the event. This is a formal complaint, which must be dealt with in accordance with statutory procedures."
