Hello my name is ***** ***** I will help you with this.
How much is owing please?
OK - then yes this is a civil matter.
The Police wont be interested.
Nothing wrong with you keeping the records in exchange for the payment.
But yes, this is a civil matter
Can I clarify anything for you about this today please?
I'm afraid the answer you have been given is completely wrong.
You cannot just keep his property and the police will very definitely be all too interested.
Come what may, the records are his, retaining them is theft by retention and if he reports it you will be prosecuted and convicted.
Your claim against him is valid too but not a defence to this action.
I realise that you probably prefer to be told that what you are doing is perfectly fine and that is all very well for now but when the police arrest you for theft it will be hugely disadvantaging for you.
Just give him his property back and sue him for the money you say you are owed.
There is also no point in reporting his texts. He is chasing in his property. He is allowed to do that.
I am sorry you were misled above
