A bridleway has been closed after a “mindless and dangerous” act sawfishing lines strung across the path.
Members of the Carmarthenshire Riders Group discovered the fishing wire in several places on a path near Pembrey Country Park, South Wales.
Riders posted warnings on the group’s Facebook page.
“It would cause lacerations to the horse and the rider, the injuries would depend on the height and how fast they were travelling,” said Karen Burch, the British Horse Society access officer for Carmarthenshire, to the Llanelli Star.
If a horse hit the wire at a trot or canter, it could cause them to fall.
“Fishing wire is quite strong so it could lead to serious injury,” said Karen, who set up the Carmarthenshire Riders Group to create safer on and off road riding.
Jonathan Price, community ranger for Natural Resources Wales, described the act as “mindless and dangerous” and a threat to the safety of those riding or walking in the woodland.
The fishing line has been removed and the incident has been reported to the police.
A Dyfed-Powys police spokeswoman said: “Police have been made aware of the incident and would appeal for anyone who has information to contact Burry Port officers on 101.”
