She admitted her involvement to police after reading the Reporter's front page story.

The incident near to a residential area in the south grounds of the historic Overtoun House saw satanic graffiti scribed and spray painted onto trees in an area used as an outdoor classroom for Garshake Nursery.

Police told how the discovery left staff “deeply upset”. The student had previously thought the effigies she was using for a short film, had been stolen when she returned to collect them.

But, just a day after breaking the news, the Reporter were contacted by both Police Scotland and West of Scotland College regarding the incident.

Inspector Neil Smith told us the incident was “due to an error of judgement” by the media student from the nearby college.

He added: “She had used the items as props in a film she was making for her graded assessment but had failed to remove them immediately after the filming finished. The student responsible has also been advised by police re her future actions.” The girl had been filming a short film about mental health with her brother and had lost track of time, filming late into the night. It was agreed they would leave the props and return to get them in the morning.

However, they were not quick enough to get to the props, which were discovered by Garshake Nursery staff.

A spokeswoman for the college told the Reporter on Wednesday morning: “All students at the college are issued with clear guidelines on the condition in which locations should be left and the importance of informing local people of what to expect.

“These guidelines were not followed in this instance and the students have been reminded about the impact of their activities on local communities. The incident has been quite upsetting for the student.”
