A man was found unconscious in a cemetery with hand and facial injuries which could have been caused by an animal such as a fox, police have said.
The 37-year-old was discovered by police at St Michael's Parish Church Cemetery in Inveresk, near Musselburgh, in the early hours of Sunday morning.
He is being treated at the Royal Infirmary of Edinburgh for non-life threatening injuries.
Police said they believe the injuries could have been caused by animals.
Scottish SPCA Chief Superintendent Mike Flynn said attacks by wild animals on humans were highly unlikely and extremely rare.
He added: "As we are not aware of the full circumstances surrounding this incident it would be inappropriate to comment any further at this stage.
"We would urge anyone with information relating to the incident to contact Lothian and Borders police to assist them in their enquiries."
Councillor John Caldwell, who represents Musselburgh and Carberry, said: "I stay not far from that area and the only animals around capable of doing such a thing are foxes."
A police spokesman said: "Lothian and Borders Police can confirm it is carrying out inquiries after a 37-year-old man was found in the Inveresk area with injuries to his face and hand.
"These injuries may have been caused by animals."
