British backpacker found dead by his girlfriend after she flew to his hostel to join him

The police were alerted by a hostel worker at midday.

The man had last been seen at 10pm local time on Sunday.

Tests are now being carried out to establish the cause of death, however, there is nothing to suggest at this time which indicates it is crime-related.

Local press claim 20 non-migrant foreigners have died this year in various circumstances in the Aburra valley - one of the country's most populous valleys in its Andean region.

Thirteen were American and another one British.

All but one died in Medellin. Only one of the deaths is being treated as a homicide.

The Black Sheep Hostel - one of the city’s most popular - describes itself as a New Zealand/Colombian-run establishment.

Earlier this month, a British backpacker’s body was discovered on Koh Tao, dubbed “Death Island”.

The traveller, understood to be 31, was participating in a pub crawl on the island in Thailand when he disappeared.

He had been travelling with his long-term girlfriend, and the pair had gotten drunk with other holiday-goers during the event on March 18.

The next morning, he was found lifeless in a shallow water drainage ditch outside the Roctapus diving centre.

Lieutenant Colonel Chokchai Suthimek, superintendent of the Koh Tao police station said: “We believe that the tourist walked and fell into a small water channel at night. He died near the Rocktopus Dive Shop at Sairee Beach.

“The police arrived and cordoned off the scene of the incident and examined the area the next day. Forensics unit arrived and also examined the scene.

“The body was sent for a detailed examination at the forensic department at Surat Thani Hospital and reported to the British Embassy to coordinate with the tourist's family.

“The case is still open. We are waiting for a report back from the autopsy. Nobody has been arrested. We think it was an accident.”
