Police have released photos of people in connection with the May 19 vandalism of Twizel's High Country Salmon.
One of the support ropes around a net at High Country Salmon was cut and about 6000 salmon released into the Ohau hydro canal and Lake Ruataniwha, business owner Peter Logan said.
Senior Constable Nayland Smith, of Omarama, said police needed the three males who appear in the photos to come forward. Their assistance could be helpful, he said, as they might have information that could assist in the investigation.
In June, Mr Logan said the fish carried a value of $20,000 as they were not fully grown, but would have been worth $150,000 fully grown. Information to: Omarama Police, (03) 438-9559.
