The pigs were stolen from the farm between May 20th and July 28th when the owner, Mats Schörling, was on holiday.
While pigs can be hunted by foxes and eagles, the farmer is surprised that they would have taken more than 60 of the animals.
Schörling suspects that the swine, which have a value of around 65,000 kronor ($7,418), were stolen.
“People who are used to handling pigs could steal two or three at a time at night. But that’s just speculation. If it happened, I have no idea,” Schörling told SVT.
Despite the farmer squealing to police, the investigation was closed after less than half an hour on the grounds that there was no “evidence or other actions that may lead to the crime being cleared up”.
The investigation has already been criticized by criminology professor Leif GW Persson, somewhat of a cult figure in Sweden and a fierce critic of Swedish police.
“Police are not fond of crime reports; they disturb their peace of mind. There are other tasks waiting to be done and of course it's to their advantage to shut the case,” said Persson.
But on Friday afternoon police revealed they had reopened the probe and had questioned the farmer, his daughter and two employees.
“It's regarding how the operation has been run at the farm,” investigating officer Pia S Kling told Swedish broadcaster SVT.
