Councils confirmed on Tuesday that absence rates were much higher than normal. Glasgow City Council said some of its schools had 50% fewer pupils than usual, while East Ayrshire Council reported absence rates three times higher than at the start of the month, with 4,881 pupils off compared with 1,600 on 1 October. Midlothian Council recorded a 21.5% absence rate across primary and secondary schools, against 6.9% on the same day last year.
James Dalgleish, convenor of education, children and families at Edinburgh City Council, urged parents to "speak to their children and calm their fears". He said: "I want to stress that we have worked with police as well as following our own safety policies and we established there was no risk to pupils. If you have any concerns about attending, please speak to your child's school. School staff will also be checking in with pupils to make sure they are safe and supported."
Hundreds of people contacted police after schools across Scotland received the emails on Monday. The warnings were quickly identified as hoaxes, and learning was unaffected in schools where pupils had returned from the October break, while other schools were still on holiday. Similar hoax emails warning of an "explosive device" were also sent to about 300 schools in Northern Ireland.
A Police Scotland spokesperson said: "These messages have been assessed and are being treated as a hoax, with nothing to suggest any threat to the public." Officers and staff from Police Scotland's Cyber and Fraud Unit were "working closely with partners" and continuing "extensive inquiries to establish the source".
