Three youths were stranded next to the River Aire in the centre of Leeds after walking along a culvert from the outskirts of the city.
The trio, aged between 18 and 21, were picked up in a fire service rescue boat near the Royal Armouries at around 5pm today.
According to West Yorkshire Fire and Rescue Service, before being rescued they had walked for several miles along along the concrete section of a culvert, a structure which allows water to flow under a road.
After reaching the end of the culvert near Black Bull Street, they were unable to cross the River Aire to get to dry land, and were faced with having to retrace their steps.
After calling for firefighters to come and rescue them, they were located by crews from Leeds and Hunslet fire stations.
A rescue boat was despatched to pick them up and take them to a ladder where they could get out of the culvert.
A message on West Yorkshire Fire and Rescue Service’s website reported three youths “trapped in a culvert on The River Aire, unable to escape due to water level”.
It added: “Youths were not in the water but were rescued from culvert using Leeds Water Rescue Boat.”
