BBC Radio 2 presenter Jeremy Vine was pulled over for breaking the speed limit on Thursday - on his bicycle.
The police officer told the broadcaster that he was cycling over three times the maximum pace for the area.
Luckily, Mr. Vine managed to capture the ordeal - on Vine.

So let this be a warning to anyone cycling, running or sauntering through Hyde Park. Stick to 5mph.
