A teenager was killed and his cousin seriously injured after being shot while playing Pokémon Go in Guatemala, reports Daily Mail.

Jerson Lopez de Leon, 18, died after being ambushed with Daniel Moises Picen, 17, on a street in the town of Chiquimula.

Nearly 20 bullet casings were found at the scene of the murder where the pair had been hunting the virtual creatures.

Local reports said the relatives were walking alongside an old railway line when bullets rained down on them from a passing vehicle.

Police are looking for the occupants of an agricultural van seen racing from the scene.

They say they are unsure of the motive but have speculated the attackers made a bungled mobile phone robbery.

Another line of inquiry is that one of the teenagers was wanted by his attackers and was located through his phone's GPS.

Jerson died in hospital. His cousin is being treated for gunshot wounds to his feet.

The dead man's mother Rosalinda said: 'I don't know why my son left the house. He was already in bed when his cousin sent him a message asking him to go out and download a game a few blocks from the house.' 

Pokémon Go has caused a rash of problems throughout the world.

Rescuers had to be called out to aid a group of 20 teenagers playing the game in the early hours of Tuesday morning when they pinched a boat and rowed to the middle of a lake.

The teenagers fled the Marine Lake in New Brighton, Merseyside, before crews arrived.

A driver was fined in Stourbridge, West Midlands, for playing at the wheel.

Two Pokémon Go players were shot at by a homeowner in Florida after being mistaken for burglars. 

Meanwhile, Bosnian users have been warned to avoid wandering into areas still littered with landmines in their quest to catch 'em all. 

And in Indonesia, police have been ordered not to play Pokemon Go while on duty and military personnel will soon be banned from the game as well, officials said on Wednesday. 

Despite Pokemon Go not yet being officially available in Indonesia, many have downloaded it illegally and taken to the streets to hunt for virtual 'pocket monsters'.

Britain's Foreign Office advises travelers: 'Don't stray from roads and paved areas without an experienced guide. 

'Unless you have an experienced guide, you should avoid the open countryside and especially destroyed or abandoned buildings, neglected land, un-tarred roads, woods and orchards, private property and abandoned villages.'
