Police teams are searching Kelso High School after what they have described as a suspicious phone call.
And Scottish Borders Council – the education authority – has confirmed there is an ongoing emergency situation but stress pupils and staff are safe.
There was a full evacuation earlier this afternoon. There has been a large police presence and fire and ambulance crews were also alerted.
A spokeswoman for Police Scotland said: “Police attended at Kelso High School at around 2.30pm following a suspicious phone call.
“Pupils and staff have been evacuated as a precaution and the building is currently being searched by police. We are liaising with Scottish Borders Council to ensure the safety of all pupils.”
Shortly before 5.30pm a council spokesman told us: “We are currently dealing with an emergency situation at Kelso High School.
“Emergency services are on site at present sweeping the building. We expect this to be completed early this evening.
“All pupils were safely and promptly evacuated from the school and are either at home or are waiting for their parents to collect them from Edenside Primary School.”
Neither the school nor the council has revealed the content of the phone call. The school grounds are sealed and guarded.
The school has an estimated roll of around 700.
