67 piglets have been stolen from a farm in Fordingbridge in Hampshire.

They each have the reference HB0789 tattooed on them.
Hampshire Police officers from the Countrywatch team are investigating the theft and want to hear from anyone who may have information.
The piglets were being kept in their family groups as they are social animals.
