The company which runs a ski resort where five children and an adult were injured when a chairlift derailed is "extremely upset" by the incident.

In a statement published on its Facebook page, Lecht 2090 said it did not know what caused the malfunction yesterday afternoon at Corgarff in Aberdeenshire.

An investigation is due to take place by the Health and Safety Executive, and the chairlift is expected to remain closed for some time.

The statement read: "We are extremely upset that these people have been injured but as yet we don't [know] the cause of the problem with the chair.

"The first response was to look after the injured. The rest of the skiers were then taken off the chairlift by the two Lecht teams in one hour and 20 minutes."

A number of comments were left on Facebook by witnesses to the accident, who praised the work of rescue teams and the emergency services.

Five children and an adult were taken to hospital after the incident.

None were thought to be in a life-threatening condition.

A Grampian Police spokesman said: "Grampian Police and Braemar Mountain Rescue Teams were mobilised to assist with the rescue of those stranded.

"Units from Grampian Fire and Rescue Service, the Scottish Ambulance Service and local doctors were also called to the scene to assist.

"Inquiries are ongoing to establish the cause of the incident."
