I see that Nick Illingsworth has said the following on The Ugly Inside ...
"Firstly the man was not an employee of Southampton football club, he had been involved with the club at one point, but he was actually a student studying a degree in Sports Analysis, he had spent time at Saints as an intern as part of a placement from his course, but he had also spent time at Derby County and other sporting institutions and since March has been at Aston Villa."
No idea if this is true or not. Is this William Salt actually not an employee anymore? If he wasn't our employee at the time then that makes a big difference to things (unless they have evidence of him doing it elsewhere while he was working for us)
