A cygnet has been left seriously injured after a "targeted" attack which left it with a broken jaw on the canal close to Royal Wootton Bassett.
Wiltshire Police believes it happened between 5 and 6 July 2019.
The animal was found on 7 July after being reported to the RSCPA and the nearby Oak and Furrows Wildlife Rescue Centre in Cricklade.
Oak and Furrows rescued the bird, who was found with two "metal nuts" in its neck and a broken jaw.
The neighbourhood policing team for Royal Wootton Bassett and Cricklade posted about the incident on their Facebook page and warned locals to be vigilant and report acts of cruelty to the police.
Cygnets are protected under the Wildlife & Countryside Act of 1981.
It has recently undergone surgery and is expected to make a full recovery and be released back into the wild.
