An American tourist is missing on the island of Amorgos since Tuesday afternoon, according to reports at MEGA TV news channel.

The tourist, who is a 59-year-old male retired police officer from the United States, went for a hike at 7 in the morning on Tuesday from the region of Aegiali on Amorgos to the port of Katapola.

The hike takes approximately four hours, so when a friend of the tourist noticed that he had not yet arrived at his point of destination by the afternoon, he declared him missing.

News reports state that the police officer has a mobile phone on him, so an application has been made to determine his whereabouts by this method.

The news of the missing hiker comes on the heels of the tragic death of the world renown Dr. Michael Mosley, from the BBC, who went for a walk on the island of Symi and died on his journey.

Authorities, throughout the country, are already on high alert due to the heat wave that is sweeping the country, which has led to the closure of schools and changes to the working hours of the public sector.

Amorgos is a remote island of the south Aegean region, characterized by its white-washed buildings, rocky terrain and sparse vegetation. It was the filming site of the French movie Big Blue and is also the home of the famous monastery of Hozoviotissa.
