Mountain rescuers responded to a mystery cry for help on a Yorkshire Dales fell, but found no-one in need of their aid.
The Clapham-based Cave Rescue Organisation was alerted by a walker coming off the summit of Pen-y-ghent who heard the sound of falling rocks followed by what sounded like a call for help.
Team members were called out on Thursday at about 1.10pm and checked out all the steep ground on the west side of the 694m (ft) hill, one of the Yorkshire Three Peaks.
No sign of anyone suffering injuries was found, although there were minor rockfalls.
A team spokesperson said the callout was being classed as a false alarm with good intent.
The previous day, the CRO went to the aid of two women lost on their way up Pen-y-ghent.
The 24-year-old and her walking companion, 31, called for help after getting lost on the approach to the fell, having already summited Ingleborough and Whernside.
Team members were mobilised at about 9.20pm and the walkers were found near Black Dubb Moss, wet and very cold but uninjured.
They were led to a team vehicle which drove them to safety.
The CRO, which carries out rescues both on the fells and in the caves of the Dales, has now responded to 46 callouts this year.
