Public nudists have come under fire in Germany as Europe sizzles in temperatures of up to 45C in the heatwave dubbed the "Sahara bubble".
In Brandenburg, police posted two pictures of a man riding a moped naked and called for captions of the images.
"Because we're speechless," said police, adding the hashtags #heat, #safetyfirst and #livingontheedge.
As contributions and queries poured in over whether the man flouted any rules, police clarified that it was not illegal to go around nude in public, but only so long as no one files a complaint.
