Need Letter Format For Terminated Employee Who Stole Company Assets

Hi all,
I work as HR admin and need to send out a legal letter to an employee who was terminated. After he left, the on-site PM reported that some of the items (assets) that the employee was using, went missing. And as per the on-site supervisors, he did use these assets before he left and had it in his bags.
Please help!!! I need to send this letter ASAP...
Thank you all for your help!!!

Dear Client this is not a case of sending a letter to the person who had already left your company, this is a case of theft which has to be intimated to the local police station under a list of names on whom you have doubts and a list of all such assets along with value which went missing. the complaint in the police station can be in your local language and there is no fixed format for this. all it is to explain the station house officer about the incident and the amount of damage the company had faced.
