No one can explain how this square-shaped fire started on a sofa in a closed shop in London. A passer by noticed it and called it on.
Clyde Johnson, from the shop, said: “We’re very thankful to Mrs Patel for phoning the fire brigade but we still have no idea how it started. It’s a fire resistant sofa luckily so it minimised the fire but we don’t know if it was caused by a laser pointer or maybe a magnifying glass or just the sun shining in oddly. The police can’t figure it out either.”
