A reward of £5,000 is being offered after the shooting of four pregnant grey seals and a juvenile in Orkney.
The shootings in Orkney have prompted the reward
The reward has been put up by the Sea Shepherd Conservation charity after the killings earlier this month.
The money will be paid to anyone providing evidence leading to a conviction.
The four pregnant females and a pup were discovered at Point of Vastray, on the west coast of Orkney. They had all been shot in the head.
The shooting of the seals was reported to the charity Orkney Seal Rescue and Northern Constabulary has also been called in.
The slaughter has prompted calls for new legislation to better protect seals.
