Walter was reported stolen from an address in the Holyhead Road area of Cemaes Bay, Anglesey, last week.

North Wales Police said Walter is believed to have been taken sometime between 4am and 6am on Thursday 18 January.

Wallabies are members of the kangaroo family, primarily found in Australia and its surrounding islands.

But with this wallaby missing in North Wales rather than generally somewhat warmer New South Wales, officers are hoping Walter will be able to be reunited with his owner soon.

Sergeant Beth Lloyd said: "Walter's owner is understandably concerned for the wellbeing of the young wallaby and wishes to see him returned home.

"We are appealing for anyone who may have seen Walter the wallaby, may have footage of the area around the time he was taken or may have witnessed any suspicious behaviour to contact police immediately."
