Detectives are investigating an arson attack on a Stoke-on-Trent house.
A resident at an address in Oldfield Street in Fenton became aware of a strange odour in the property at about 7:30pm last night.
A short time later, after a knock at the door, she realised the letterbox had been set on fire.
Fire crews were sent to the property, but the fire was already out before their arrival.
The offender was seen running away from the property, jumping over a wall into a nearby alleyway.
He is described as a white boy, aged between 10–14 yrs-old.
Police are appealing for anyone with information on the incident to call them on 101, or contact Crimestoppers anonymously on 0800 555 111.
