A 46-year-old man has been arrested after a series of racist mock Pokémon stickers appeared at London Tube stations and bus stops.

British Transport Police launched an investigation last week after “disgusted” commuters discovered the stickers, branded “P***mon”.

The stickers mimicked the popular children’s card game where players are awarded points for collecting Pokémon based on their rarity.

Offensive stickers featuring Mayor of London Sadiq Khan and former member of the self-styled “Muslim patrols” Jordan Horner were spotted at Borough Tube station in south London.

A 29-year-old man, from Clapham, who asked not to be named, shared a picture of two of the stickers on social media.

He told the Standard he wanted to show other people how “appallingly racist” they were.

A 46-year-old man from Sutton, London was arrested by British Transport Police on suspicion of inciting racial hatred on Thursday.

A BTP spokesman said: “The arrest, which was supported by officers from the Metropolitan Police, is in connection with the appearance of racist ‘Pokémon’ style stickers on the London Underground and at bus stops throughout the capital.

“The man remains in police custody as enquiries continue.”
