A health and safety body is looking into an injury to a worker at a north-east construction site.
The Health and Safety Executive (HSE) is in the early stages of inquiries into the incident in Inverurie.
It happened at the site where the new Inverurie Water Treatment Works is being built.
Ambulance crews were called out just after 5pm on Thursday after a man was injured while working underground.
The Scottish Ambulance Service as well as Police Scotland and the Scottish Fire and Rescue Service were at the scene.
The man is recovering at home after being released from hospital.
An HSE spokeswoman said: “HSE is aware of the incident and making initial inquiries to determine the extent of the injuries and whether this meets HSE’s investigation criteria.”
A spokesman for Scottish Water said: “Emergency services were called to the construction site of the new waste-water treatment works being built in Inverurie. A member of staff working for the contractor involved in the project was injured.
“He has since been released from hospital and is recovering at home.
“We wish him a speedy recovery.
“A full investigation into the circumstances surrounding the accident is under way.”
