Saw this on Facebook, posting here in case anyone in Pembrokeshire can help.
Approx 14hh dark bay horse with tack on found apparently heading towards Herons Brook.
No box or trailer so must have hacked there.
If anyone knows of anyone hacking out there today who hasn't returned please contact 101 as the police are trying to locate the rider.
There hasn't been an update on the Facebook post so I'm assuming the rider hasn't been found yet.
