This time the finger of suspicion is pointed at a wallaby, who police think was behind a break-in in Henley-on-Thames, London.
It follows the case of monkey, who earlier this week was accused of stealing a mobile phone.
In this new incident, a woman in the flat returned home to find a broken window - so she called the police thinking she might have been robbed.
They tested blood found at the scene - and discovered it belonged to a wallaby, not a person.
Police think the unlucky animal fell into the basement of the house, before breaking the window to make its escape.
And with nothing being stolen, it appears it was all a terrible accident.
