Police are appealing for information after a newborn micro pig and a guinea pig were stolen from Newham Grange Country Farm in Middlesbrough.
The black micro piglet, which is just four days old, was snatched when a woman poured water on the mother of the piglets to get her to move away from them.
She also stole a guinea pig before running from the farm into an awaiting silver Ford Focus Zetec.
Police believe that the woman had entered the pens on a number of occasions and had been asked to leave.
The woman was accompanied by another woman, a man wearing a blue tracksuit, a small blonde child and a baby.
One of the women is described as having red hair, is white and of heavy build.
Anyone with any information is asked to contact PC Lyndsay Dale on 101 or Crimestoppers on 0800 555 111.
