An abandoned dog, canoe and wetsuit prompted fears someone may be in trouble in the water at a beauty spot in the Broads.
Emergency services raced to the scene at Horstead Mill, near Coltishall, after a member of the public raised the alarm around 8.20pm on Thursday.
Fire crews from Wroxham, Martham and Carrow, along with a rescue unit, joined Hemsby Lifeboat, Mundesley and Happisburgh Coastguard team, a Coastguard helicopter from Humberside, and police to search the area.
The ambulance service was also on scene.
However, they were stood down around 10pm after failing to find anything.
A spokesperson for the Coastguard said: 'A member of the public has seen a few things that had concerned them, including a dog abandoned in area.'
But he added: 'The owner has since come forward.'
Daniel Hurd, coxswain at Hemsby Lifeboat, said the owner of the canoe had also been found. He added: 'Everything pointed towards there being someone in the water but thankfully we've been stood down.'
