Three people have died after a crash involving a bus and two cars in Aberdeenshire.

Four people were also taken to hospital after the incident on the A90 between Aberdeen and Dundee at Glenbervie, which happened around 4.30pm on Tuesday.

Their injuries are said to be serious but not life-threatening, and they are being treated at Aberdeen Royal Infirmary.

None of the passengers on the Scottish Citylink bus were hurt – but the driver sustained minor injuries, police said.

Police Scotland road policing chief inspector Stewart Mackie said: “This has been a challenging incident for the emergency services to deal with and my thoughts are with the families of all those affected by this.

“I would ask that anyone who witnessed the incident and who hasn’t already spoken to the police contacts officers on 101 using reference number 2576 of March 12.

“The road is anticipated to remain closed for some time to allow collision investigation to take place.

“This is likely to be a complex enquiry that will take some time and I am grateful to the public for their patience while this is carried out.”

A Scottish Citylink spokesman said: “One of our coaches travelling from Glasgow to Aberdeen was involved in a serious multi-vehicle accident this afternoon on the A90 near Glenbervie Junction. Our immediate thoughts are for those involved in the incident.

“Safety is our absolute priority and we will assist police with their inquiries into the circumstances. There were no reported injuries to passengers travelling on the coach and they were provided with alternative transport to take them to Aberdeen bus station.”

The road was closed in both directions and the public advised to avoid the area.
