“They worked on her on Thursday and Friday and on Saturday she went to an emergency vet. “She just went down hill. She couldn’t swallow the tablets because when she threw up it burnt her throat.” Susan, who runs Middlesbrough’s homeless cafe, in Princes Road, said she had heard other anecdotes of the same thing happening to other people and urged others to report it if it happened to them. She said: “I really want to see someone caught and to make it safe for people. “If it happens to people they should call the police. If people see something in the parks they should report it, don’t ignore it. We need to find out what is happening. She added: “It was a horrible death. My son is absolutely heartbroken. “I just hope it doesn’t happen to anyone else or any other wildlife.” She said she had been in contact with the manager of the park about the issue. The issue has sparked dozens of comments from people online voicing concerns. A Middlesbrough Council spokesman said: “We have not been made aware of any pets taking ill after visiting Albert Park – but urge anyone with evidence to come forward and report it to the council and to Cleveland Police. “Middlesbrough Council staff will continue to maintain and monitor the park as normal. “We are also aware of a photograph circulating on social media which appears to show a sign attached to the gates of Albert Park, warning cat and dog owners against visiting. The picture is not real and has been edited, and no such notice has been placed on the park gates.” Keep up to date with all the latest news on our website, or follow us on Facebook, Twitter and Instagram.
