A wallaby
A wallaby and its joey is on the loose in County Down after it escaped captivity in Clough, Downpatrick.
Police have urged locals to be on the lookout for the animal but not to approach it as it could be dangerous.
The privately owned animal has been missing since Friday night and left with its joey in its pouch.
Officers have asked the public to contact the police on 0845 600 8000 if they see the animals.
Two years ago a wallaby escaped its enclosure in County Tyrone.
It was later found in County Londonderry.
