Neil Lennon wants 'heads to roll' at the Scottish Football Association after a secret dossier on his Old Firm bust-up with referee Stuart Dougal ended up in the 'wrong hands'.
One of the Celtic skipper's advisers Martin Reilly has revealed the blunder by Hampden Park chiefs after the dossier, compiled following the midfielder's dismissal in last August's defeat at Rangers, was found in a skip half a mile from the national stadium.
Lennon is said to be furious with the mistake and is demanding drastic action be taken.
Reilly told the Scottish Sun: 'Neil isn't happy with the situation at all. We're looking into the incident and will be asking the SFA for an explanation. And it's something we'll be discussing with our legal department.
'At the end of the day someone should be getting hauled over coals for this. As far as we're concerned heads should be rolling at the SFA.
'This is simply something which should not happen. How can paperwork, which is purely confidential, all of a sudden end up in the wrong hands?
'Our client's name and address is obviously something he wants to protect. Is this an innocent mistake or has it been done deliberately because it's Neil Lennon?'
