Police are under investigation for jokingly filling in a witness statement in the name of a force dog.

Officers became exasperated when prosecutors asked for an account of a crime from a ‘PC Peach’, not realising Peach was the name of a police dog.

So they completed the form as if it had been written by the alsatian, and signed it with a paw print.

The dog’s statement read: ‘I chase him. I bite him. Bad man. He tasty. Good boy. Good boy Peach.’

The form was pinned up at a West Midlands Police station last week for the amusement of colleagues, who are often at odds with the Crown Prosecution Service (CPS) over the handling of cases.

Another officer took a photo of the statement and it found its way to a ‘cop humour’ page on Facebook on Friday.
