Owners asked to keep horses safe in Northamptonshire
Horse owners in south Northamptonshire have been asked to ensure animals are held in secure compounds after several were found loose on public roads.
Police issued the warning after several horses in the Ashton and Hartwell area were found on the loose.
Officers suspect someone may be deliberately opening yard gates and letting animals out.
Police have advised owners to make sure their animals are housed securely at all times.
"Gates should be shut and padlocked on both sides," a police spokesman said.
