Emergency services were called out to Clifton Bridge in York this afternoon.
Police, fire engines and ambulance crews went to the scene after a member of the public reported seeing a body in the water.
Happily, it was a false alarm.
A North Yorkshire Police spokesperson told YorkMix: “It was initially reported by a member of the public as a possible body in the river.
“We attended along with fire service personnel, but it turned out to be a floating piece of canvas material.”
A Yorkshire Ambulance Service spokesperson said: “We received a report for concern near Clifton Bridge York on Monday afternoon and ambulance and fire service resources attended the scene.
“They were subsequently stood down.”
