Inspector John Cooke said: “This was an appalling incident leaving a man seriously injured and I want to make it clear that we will not tolerate irresponsible dog ownership.

“It is a criminal offence to allow a dog to be dangerously out of control and dog owners have a responsibility to ensure their dog does not inflict such terrible injuries on anyone.

“I would also ask anyone with information about this incident or dangerous dogs in their area to contact us so that we can take action."
