Vandals spray painted 'Free Luke Mitchell' graffiti outside a police station in Midlothian.
The words were seen scrawled across the Dalkeith station alongside the slur 'ACAB' which stands for 'all cops are b*******'.
The damage follows a string of similar incidents after a Channel 5 documentary on the murder of teenager Jodi Jones, who's body was found near her home in Easthouses, Midlothian in 2003.
Her boyfriend Luke Mitchell was jailed for a minimum of 20 years in 2005 for the 14-year-old's murder.
He has lost several appeals on evidence he has presented to overturn his conviction.
Posting the pictures on Facebook, one local resident said: "Some one spray painted the ramp at the back of the cop shop in my area, bloody vanzalized."
In March angry residents hit out at vandals after graffiti with the words "Free Luke Mitchel" appeared in a Grangemouth park.
It was spotted on a small electricity building by a member of the public in Zetland Park, which is currently going through a £192,000 regeneration project.
The building, situated near the play park, also has the words "Retrial Now" and "Justice 4 Luke" sprayed over it.
It has caused outrage on social media, with one person saying: This is disgusting, our lovely park targeted by wasters again. What is wring with people?"
