Thank you for your advice.
In regard to the files that the former employee took, they made a copy of all the customer files which include artwork, layouts, etc. that were created by the former employee and other employees. A large portion of these files contain work that was completed to produce the products the customer wanted.
I hope I can explain this clearly. To produce the product customers required, my employees had to create the artwork. The former employee has copies of all this work, which includes work that I paid him to as an employee, and artwork that was also created by other employees for use in my business. He has this artwork and is using it to bid on my customers. There are two ways that artwork is created, one is paid for by the customer to use as they need to. The other is artwork that my employees have created for my business that the former employee is now using as well.
I have also discovered that he indeed make a copy of my customer database, and is using it to contact my customers.
I understand that case of the former employee targeting my customers is a civil one. Is there a case to be made for the artwork that is property of my company that he is now using at another business?
