It seems that word still hasn't reached some visitors to Rome that it is against the law to take a dip in the capital's fountains.
In the early hours of Sunday morning, six British tourists stripped off and leapt into the Fountain of the Naids in Piazza della Repubblica, Il Messaggero reported.
Despite the time of day, their antics attracted a small group of onlookers, who reported the incident to the police.
Within minutes, the police were at the scene, and swiftly charged the six tourists, who ranged in age from 25 to 49, with indecent exposure and for jumping into the monument.
On top of a criminal record and the embarrassment, anyone caught frolicking in Rome's fountains, or throwing rubbish into them, faces a fine of up to €200.
The fine amount was increased this summer following a spate of incidents in which tourists used fountains to cool off amid an intense heatwave, with one even being seen by President Sergio Mattarella, who just so happened to be passing by.
Frustrated Rome residents have also taken to social media to shame tourists they spot indulging in a fountain dip.
