A radar clocked someone going nearly double the speed limit. It turned out to be a duck — and a "repeat offender."

A radar image of a speed offender caught in central Switzerland last month revealed that the culprit was not only a duck, but likely a "repeat offender," local authorities said.  

Police in the town of Koniz, near the capital Bern, were astounded when they went through radar images snapped on April 13 to discover that a mallard was among those caught in the speed trap, the municipality said on its Facebook page over the weekend.

The duck was caught going 52 kilometers per hour (32 mph) in a 30-km zone, the post said, along with a photo of the fast fowl.
