Fire crews carried out a water rescue at Beeston Weir.
A spokesperson for Nottinghamshire Fire and Rescue Service said:
‘A narrow boat got into trouble at Beeston Weir and was marooned on the hydro sub taking on water with a male trapped on board.
‘Working with the Canal and Rivers Trust we were able to free the craft which carried safely on its journey.
‘Crews were also supported by Long Eaton Fire Station and our specialist rescue team from Newark Fire Station.
‘A tactical commander also attended.
‘The incident happened at Owen’s Place which holds a special place in our hearts and we took a few moments after the incident.
‘Over the next few weeks, we’ll be kick-starting our summer water safety campaign and you’ll see lots of activities from us. We have a very clear aim, and that’s zero accidental drownings.’
