Pink pellets that could be potentially harmful to dogs have been left at the foot of trees in Hertfordshire.
Police are urging animal owners to be vigilant following the discovery on the Wheathampstead heritage trail in Devil's Dyke.
The pellets have now been removed with samples taken for testing by officers. They were first found on Saturday January 21 but were not reported to police so they could be cleared up until January 23.
"The pellets are currently being tested but it is highly likely they could be harmful to dogs or other animals. If you were in the area with your dog over the weekend and they seem unwell, please taken them to the vet to be checked over.
"Until we know what the pellets are, we want to make sure people are aware as a precaution."

A single village in Suffolk is sending no less than EIGHT dogs to this year's Crufts.
Four breeders from Mendlesham near Stowmarket are all heading to Birmingham's NEC Arena for the four day show.
Four breeders - Kay Crisp, Debbie Gaskill, Sharon Marshall and Isabel Eastall own dogs of four very different breeds - Cocker Spaniels, Dachshunds, Afghan Hounds and an Airedale Terrier.
They say it's a complete coincidence that they all live in Mendlesham, but the village and surrounding area is full of dog lovers.
And it's not just the village that has pedigree - Cocker Spaniels Dexter and Mini are descended from a Crufts Best in Show winner.
A service aimed at helping children and families get over a 'fear of dogs' visited Chelmsford to raise awareness of the scheme. The Essex Dog Training Centre at Brentwood has the only trained Cynophobia assistance dogs in Europe.
