Police have again renewed their plea for information about the killing of a seal in the River Wyre six months ago.
The plea came after the arrest, and release, of a 28-year-old man, of no fixed address, who was questioned on suspicion of inflicting unnecessary suffering to a wild mammal.
After being interviewed, the man was released without charge.
Courier inquiries prompted a request for anyone with information about the shooting of the seal, known locally as Sammy, six months ago, to contact them.
The shooting, in the Little Eccleston area of the river in March this year, prompted anger among animal lovers.
At the time Lancashire wildlife officer PC Mark Thomas said he was appalled and disgusted.
He added: “Incidents like this cannot be allowed to happen and the person who has done this needs to be brought to justice.”
