"Runaway cows shot dead by armed police during seven-hour stand-off"

Spotted by View From The Solent in The Telegraph:

Two escaped cows that went on the rampage have been shot dead during a seven-hour stand-off with armed police, who scrambled a helicopter to hunt down a third escaped animal.

Officers were sent to hunt down the cattle after they escaped from Norwich Livestock Market as they were being loaded on to a lorry by their owner, on Saturday afternoon.

Armed officers were sent in to shoot the cows, with the agreement of the owner in the "interests of public safety", Norfolk Police said. A third escaped cow, which managed to evade capture by police, was found dead in nearby woodland at around midnight...

A stand-off? Was it an armed stand-off, and if so, who armed the cows? Were they surrounded by police calling them to surrender through a loud hailer? How did the third cow die? Did they find it next to a pistol and an empty whiskey bottle?
