Police threats have stamped out a Naked Pumpkin Run that has become a modern Halloween tradition in a US city.
Dozens of partygoers in Boulder, Colorado, have in recent years run down the streets dressed only in shoes and a hollowed out pumpkin on their heads.
But this year police placed 100 officers on the streets and threatened that anyone found naked would face a charge of indecent exposure, which would mean being registered as sexual offender. Few took the risk and police made only one arrest.
