CCTV footage has been released showing vandals plastering obscene slogans on GlasGLOW displays.
The video has been issue by show organisers after the shocking incident at the Botanic Gardens event in the early hours of Saturday morning.
Two so-called protestors can be seen spraying 'no Tory c***s allowed' on a banner while another looks directly at a camera and smiles before writing 'Greta was here' on a model dinosaur fossil head, the Daily Record reports.
