A police investigation is under way after a Swiss Army-style knife was discovered at an Angus primary school last week.
Parents with children at Southmuir Primary in Kirriemuir have been informed of the incident, which took place on Wednesday.
Pupils at the school were sent home with letters for parents in their bags on Friday.
The find at the primary school has been linked to a theft from the BP service station on the town’s Lindsay Street.
The police and Angus Council are working together to investigate the incident.
A police spokeswoman said: “Police Scotland is making inquiries into the theft of multi-tools from BP service station, Lindsay Street, Kirriemuir, following the recovery of a multi-tool at a primary school in Glamis Road, Kirriemuir, on Wednesday November 11.
“Officers are working with the education authority at Angus Council regarding the matter.”
The discovery prompted some debate on social media on the Oor Kirrie Facebook page after a parent posted information online in case some parents did not check their child’s schoolbags.
Some people noted that in previous generations it was seen as acceptable for children to carry pocket knives.
A contributor said that 50 years ago every boy in Kirriemuir had a “knife in his pocket at some time or another”.
One man said: “I’ve had a pocket-knife of one form or another since I was eight.
“I’m now 70 and I’ve never yet killed or even maimed anyone.”
Another man said: “Wouldn’t be the first time a pupil has taken something inappropriate to school, sure it won’t be the last.”
An Angus Council spokesman said assistance was being offered to the police.
He added: “Appropriate advice has been given to pupils and parents following the recovery of an item at an Angus primary school last week.”
