Dog owners have been told to be careful after black puddings stuffed with razor blades, glass and pills were found in Stoke-on-Trent.
Police have been called in after photos emerged on social media of the treats concealing dangerous items in Burslem.
At least two black puddings have been discovered in the Camoys Road area of the Mother Town.
It is not yet known if any dogs have been harmed.
One resident said: "How disgusting. What goes through people's minds?"
And another added: "This is ridiculous, people are scum."
To report any suspicious items, call Staffordshire Police on 101.
