A mother has warned of the dangers of Pokémon Go after she says a robber threatened to kill her nine-year-old son who was playing the game in Ealing .
Natalie (who asked for her surname to be excluded) said her Pokémon-obsessed son James was in Acton Park with a friend aged 13 when they were subjected to the terrifying ordeal on Wednesday (August 3).
She said the boys were playing the augmented reality game that morning shortly before 11am when they walked past a man near the playground who asked if they had any credit.
When they told him no, he asked to use their phones, and when they refused, she says he started chasing them.
"He threatened to kill them if they didn't hand over their phones and when they did so he told them to stay still and not go for help as he rode off on his bike," she said.
"James loves Pokemon and had been playing the game for about two months but this has totally ruined it for him.
"They were both very shaken and James doesn't want to play Pokémon anymore.
'How could anyone do this to children?'
"It was the first time he's been out without me and it should have been a happy occasion but I'm worried this will shatter his confidence.
"Doing this to anyone is terrible, but how could anyone do it to a couple of children?
"Parents need to be warn their children to keep their phones out of sight and be careful when playing Pokémon Go."
Natalie said her son was using her phone, a Samsung G3, and his friend was using his father's iPhone.
She said police had driven her and her son around the area that morning but they had been unable to find the robber.
getwestlondon reported last month how police in Westminster had warned Pokémon Go fans to remain alert after phones were stolen from two people playing the game on the same day.
The robber is described as a white man aged 20-25. He was wearing black tracksuit bottoms and a black hooded jumper, and rode a white bicycle.
