More than 30 police officers in riot gear surround a suburban house. Some are carrying rifles.
But this was not a deadly stand-off with an armed gang or a lone gunman.
Instead the huge police operation was aimed at two dogs. It went on for 30 hours and is estimated to have cost £30,000.
It only ended when a vet more used to tranquillising lions finally went into the house with two officers and subdued the dogs. They were later put down.
The animals had turned on a teenage friend of their owner while he was looking after them. Daniel Boardman, 19, was badly bitten on the legs, arms and bottom but somehow managed to dial 999.
Two armed officers arrived to find Mr Boardman being pulled in opposite directions by each dog. They broke down the door and shot the dogs with Taser stun guns to free him and drag him to safety.
But then, because of the danger they posed, the dogs were left in the boarded-up house in Rishton, Blackburn, for 24 hours with a guard outside.
