PEOPLE sleeping in a house in Exeter escaped unhurt after pranksters put a lighted firework through their letterbox in the early hours of Sunday morning.

The firework caused slight fire damage to the ground floor while the rest of the house was heavily smoke-logged.

The occupants of the house, in Monks Road, Polsloe, were woken up by a smoke alarm.

Fire crews used a positive pressure ventilation fan to clear the smoke.
