Two teenagers were airlifted to hospital after getting into difficulties while swimming at the mouth of a river.
The youths had managed to scramble to the shore by the time the Peterhead lifeboat arrived at the scene at the port’s Craigewan beach.
The RNLI vessel was launched after coastguards were alerted that the duo were in difficulty in the River Ugie.
They were treated at the scene by paramedics before being flown to Aberdeen Royal Infirmary by an RAF Lossiemouth-based Sea King search and rescue helicopter.
The incident happened around 12.45pm on Saturday.
The youth’s condition was not known last night.
Meanwhile, the lifeboat was called out a second time on Saturday to help tow a broken down jetski back to shore.
Its rider had earlier managed to abandon the machine and climb on to rocks at Peterhead’s harbour.
The incident happened shortly before 4.20pm.
Earlier this the year, two youngsters had to be rescued after getting into difficulty in the sea off Fraserburgh’s beach.
Scott MacLean, then 12, and Isla Sim, 13, were pulled to safety by Fraserburgh’s lifeboat crew after spending more than 20 minutes stranded in the water.
Rescuers said Scott was moments from drowning during the July incident.
A few days after the incident the two children were reunited with the lifeboat heroes who saved them.
A spokesman for Peterhead RNLI said the Ugie incident could have been similar.
“The only difference was that the kids managed to get to shore,” he said.
