A British man was reportedly found dead with one hand tied to the deck of his sunken sailing boat in the port of Souda, on Sunday.
The Greek Coast Guard and the Souda Port Authority reportedly attended the scene after fishermen found the sunken vessel.
Authorities are now investigating the mysterious death of the 70-year-old.
According to reports, the British man had been living on the boat with his dog since his wife's death ten years ago.
The man's dog was located alive and was taken to a local welfare society.
The 'Animal Protection' society posted on social media that "fishermen spotted the dog on the sailboat mast in the water."
It added: "The animal was whining and was desperately trying to hold on to the wreckage of the sailboat to avoid drowning.
"Unfortunately, the guardian of the dog, who is an English citizen, was found dead."
"Please anyone who can foster the dog temporarily, so that the police can look for the family of his unfortunate guardian."
