A discarded tent sparked a major police and fire service operation on the River Ribble at Preston today.
The emergency services turned out after reports from members of the public that a "body shaped" item was floating in the water.
A boat from Lancashire Fire and Rescue's Water Incident Unit at Penwortham was launched near to the bridge in London Road.
The brigade also used a drone to try and identify what the object was.
It was found to be an old tent and was recovered from the river further downstream near to Strand Road.
A spokesman for the Penwortham crew said: "Someone had seen something floating in the water and, the way it was structured, it could have looked like a body.
"We launched the boat to go downstream and take a closer look. It turned out to be a blue tarpaulin type of tent which had been discarded.
"We just checked it out and recovered it further down near to the cadet hut on Strand Road."
