A piece of art worth up to £50,000 has been destroyed, police have said.
The piece, a netted web made of fishing line, called "Over Here", was being displayed at an outdoor exhibition at Jupiter Artland on the Bonnington Estate in Edinburgh.
Detectives said it had been torn from trees where it was hanging and stretched out of shape sometime between Sunday 17 July and Monday 18 July.
The artwork, by Shane Waltener was valued between £40,000 and £50,000.
A spokesman for Lothian and Borders Police, said: "This has been a mindless act of wanton destruction that has resulted in one artist's creation being completely destroyed.
"Anyone who was in or around the Bonnington Estate on either Sunday or Monday and remembers seeing any suspicious activity is asked to contact police immediately."
Jupiter Artland is a non-profit "sculpture garden" open to members of the public and located in the private grounds of Bonnington House.
