A parent has complained after Yes campaigners canvassed children at the gates of a Tayside school.
A concerned mother with two boys at Monifieth High School said teachers confiscated Yes badged items for fear of playground fights breaking out.
There are no rules preventing political campaigners from canvassing outside schools, but the Electoral Commission says it depends on how the activities are perceived.
The mother, who asked not to be named, said she was “annoyed” that the group had set up in the area.
“My sons came home at lunch and said they (the campaigners) were right outside the school gates.
“They said teachers were telling them to put stuff away in their bags or taking it away from them.
“To bring that to the school gates is obviously going to set children against each other.”
A spokeswoman for the Electoral Commission said campaigners are free to canvass public places as long as they are not behaving in a threatening or abusive manner that could be deemed offensive.
Doug Muir of Yes Angus said they had acted in a friendly and responsible manner.
Mr Muir added: “We are reaching 16 and 17-year-olds who are voters and that is democracy I cannot see anything wrong with that.
“We are there handing out leaflets and if they want to accept them then that’s fine.”
An Angus Council spokesman said: “As this was taking place outside the school grounds we have no jurisdiction in the matter.”
