It is thought Vaseline had been smeared on the banister as a prank
An investigation is ongoing at a secondary school after a janitor was injured when Vaseline was smeared on a banister as a leaving-day prank.
Linda Gillie slipped on the stairs at Galashiels Academy and suffered a head knock and bruising to her body.
She was treated overnight at Borders General Hospital last Wednesday and is now recovering at home.
Head teacher Kathleen Angus described it as an "unfortunate accident" which would be investigated thoroughly.
Senior pupils on the verge of leaving the secondary are thought to have been responsible as part of what has now become known as "muck-up" day.
A spokeswoman for Scottish Borders Council said an investigation was under way.
She said: "We can confirm that a member of the janitorial staff fell at Galashiels Academy while cleaning what was thought to be Vaseline from a banister on one of the stairwells within the school.
"The school is currently investigating the incident to ensure those who are responsible are appropriately dealt with."
Councillor Catriona Bhatia, the council's education convener, said it was possible some form of action might be taken.
"We appreciate that young people want to celebrate leaving school but we don't want them causing a danger to other people," she said.
"If they are not going to act responsibly they shouldn't be allowed into school."
