Police are appealing for information after three cars were broken into at a popular climbing venue.
Items stolen include sports gear and a rucksack in the raids on the vehicles at Stanage Edge in the Peak District two weeks ago.
Police at nearby Hathersage said the incidents happened between 10am and 5pm on Wednesday 14 November.
Clothing was stolen from an Audi A4; a rucksack, clothing and sports equipment from a Toyota Hiace, and an Alfa Romeo had its window damaged.
PCSO Anthony Boswell from Hathersage Safer Neighbourhood Team said: “We would like to remind all motorists that when leaving their vehicle unattended to remove any valuables from display.
“Do not put valuables in the glove compartment as this is the first place a thief will look.”
Record-breaking Everest summiteer Kenton Cool Tweeted on 14 November that his car had been broken into. Mr Cool, who has reached the top of the world’s highest mountain 10 times, said: “Great day somewhat spoilt by someone breaking into the car.”
He was at the gritstone edge with fellow Sherpa Adventure Gear athlete Neil Gresham, testing some of the brand’s gear.
Police said anyone with information is asked to contact PCSO Boswell quoting crime numbers 49122/12, 49130/12 or 49134/12 using the non-emergency number 101.
The crimes can also be reported anonymously to Crimestoppers on 0800 555 111.
