It was reported that a man entered a shop in Sandgate Road at around 1.50pm on Tuesday 20 July 2021 and approached the till area.
He asked for a box of Pokemon Darkness Ablaze cards and when he was told the price, he reportedly showed shop staff a knife and told them to place the cards and money from the till into a bag. He then left the scene.
