A 36-year-old British national was found dead in his home in Larnaca on Thursday, with initial police investigations ruling out foul play for the time being.
The man was found dead in his home in Livadia at around 4pm.
Colleagues who had missed him at work over the past three days went to his residence looking for him.
The man was lying unconscious on the floor of his kitchen.
No trauma was visible on his body.
An autopsy is to be carried out on Friday.
