It is not clear which authority carried out the operation on Wednesday.
"It's not our case, but we are there assisting another authority. It's not a police case," says Patric Fors, a police spokesperson, to TV4 Nyheterna.
The County Administrative Board has previously pointed out errors and shortcomings at the farm, but does not want to provide any information on the matter.
The dairy farmer on the farm has been suspended after the program aired on Tuesday.
