Trying to Find Old Friend Limassol / Nicosia

Hi, I am trying to locate an old friend of mine. He was the manager/owner of Panktoris duty free shop in Limassol many years ago in the 90s and for many years after PANKTORIS Duty Free Ltd. He was thinking to run some Post offices. I am sure he or his son are still in a business or in Cyprus some where.

He was also the owner of many casinos on cruise ships at the time and maybe part of the Casino business on land in Cyprus now. I worked for him as a Casino manager and we were really good friends.

His main office was in Nicosia, I can't remember or find the address to locate him. I have old phone numbers, but they don't work anymore.  He must have closed it.

I do have a few more details about him and his son, but I can't add personal details on here. If you message me through private messages, I can give a few more details.  I really want to find him or his son again. 

I went to Cyprus this year, but all the shops and places have changed and of course all the phone numbers too.

I can't think of a way to find him. I am English not Greek, but I lived in Cyprus on and off for years.
