RSPCA Chief Inspector Rob Melloy said: “Poor Bruce is still extremely poorly and at this stage we are taking it hour by hour as to if he will pull through given the horrendous nature of his injuries. But he has shown he is a fighter and it really is a miracle that he is still with us.

“Yesterday he underwent surgery and his eye was removed, but the sheer extent and severity of his injuries means that his prognosis is still uncertain , vets are doing all they can to give him a fighting chance – we are all just willing him to pull through.

“We have been overwhelmed by the support from the public and offers of help and we are truly grateful to everyone for their concerns for poor Bruce.

“I am doing all I can to bring the person responsible for this crime to justice and I would urge anyone who has information to please contact me via our cruelty line or reporting it to us online. All information will be treated in the strictest of confidence.

“While it is understandable that a case like this will evoke a strong emotional response, we would ask people to refrain from sharing speculation of who may have committed this offence online. Any information should be reported to us via the appropriate channels because if not this could compromise our investigation.

“Please call our appeal line on 0300 123 8018.”
