A British man has been stabbed to death in woodland in Portugal.
A 26-year-old also described as British has handed himself in to police and reportedly confessed to the killing.
The victim has been identified as a 35-year-old.
Local reports say the knife attack happened during a row while a group of friends were playing the notorious Blue Whale suicide game, the online chalenge which has been linked to numerous deaths around the world.
Police found the victim’s body in remote woodland between the localities of Poco Negro and Soalheira, near to the town of Pedrogao Grande, on Sunday.
They had been alerted by friends of the dead man, around 6.30am on Sunday, who accompanied them to the scene.
One of the friends is said to have confessed to killing him.
The ongoing investigation is being led by Portugal’s Policia Judiciaria force.
Detectives spent Sunday questioning at least three men and two women, including the Briton described as the chief suspect.
It was not immediately clear on Monday how many of them will be ordered to appear before a judge in court and when the court appearance will take place.
The group that raised the alarm are thought to have attended a private party on Saturday night near to the area where the dead man’s body was found before heading to the remote woodland spot.
The PJ has yet to make any official comment.
A forest fire in June 2017 which broke out near the central Portuguese town of Pedrogao Grande killed 64 people and injured more than 250.
The British man said to have confessed to the killing went to a GNR police station in the village of Figueiro dos Vinhos about a 15-minute drive from Pedrogao Grande, to tell officers what had happened.
A National Republican Guard source told local press: “He was accompanied by two other people who had witnessed the incident.”
The knife he allegedly used is said to have been recovered at the scene after they went with officers to the remote woodland spot where the British man’s body was found.
A post-mortem was expected to take place today in the university city of Coimbra.
The PJ force in Coimbra is also in charge of the ongoing investigation.
The people questioned by police, including the suspect, are thought to be part of a group of foreigners living in a commune near to the crime scene. They have been described locally mainly as British and Dutch nationals.
Footage published by Portuguese daily Correio da Manha showed GNR officers lifting the dead man’s body on a stretcher after it was covered with a sheet and putting it into the back of a nearby police van.
A waiting Red Cross ambulance took it to Coimbra after police reached the nearest tarmacked road.
