Councils say checks would take too long

don’t know how many have had knives. “Surely every school should know without having to search through every pupil’s record?

“If someone at my kid’s school had a knife, I’d certainly want to know.

“If they’re not keeping track, how else can they check if things are getting better?”

An inquiry ruled 16-year-old Cults Academy pupil Bailey’s death was “potentially avoidable” if teachers had been told that a pupil carried weapons.

His killer, who cannot be named, was later jailed for nine years after being found guilty of culpable homicide.

A five- day trial at the High Court in Aberdeen heard the incident involved an argument over a biscuit.

A friend of the boy who killed Bailey told the court he had shown him a knife and knuckledusters on several occasions from the end of 2014.

Police Scotland said last year that there had been 15 knife incidents at Aberdeen schools between October 28, 2015, when Bailey died, and October 2016, taking the total number in the last 22 months to 35.

In Dundee, eight incidents have been recorded since the start of the 2015-16 school year, as well as a further seven in both East Ayrshire and Glasgow, and six in Shetland.

Angus and Clackmannanshire recorded five each, Argyll and Bute and Inverclyde two each, and Stirling and Renfrewshire one apiece.

Edinburgh, Dumfries and Galloway, Falkirk, Highland, North Ayrshire, South Ayrshire, North Lanarkshire, South Lanarkshire, West Dunbartonshire and West Lothian councils said they could not provide the information because it was not held centrally and it would require searching each individual pupil’s record, which would be too time-consuming.

Aberdeenshire, Midlothian and East Lothian councils said they could not provide figures
