Six nude sunbathers have each been fined £80 by police in Merseyside after stripping off on a beach.
The bathers were caught without their clothes on in the sand dunes at North Sefton and were issued with fixed penalty notices.
Police launched Operation Crow with English Nature Sefton Rangers after complaints by residents and visitors.
The operation will target nude sunbathers throughout the summer, particularly on hot days, police said.
Pc John Schofield, of Merseyside Police, said: "This type of activity is not acceptable to the many families with young children who like to go out and enjoy the sand dunes on a sunny Sunday afternoon.
"We will continue to address this problem and will give penalty notices to anyone responsible for public order offences."
