Kanye West and Bianca Censori are under investigation by Italian police for allegedly violating "standards of public decorum" during an explicit boat ride.
The boat's operator is set to be questioned after explicit photos of the couple emerged, possibly leading to legal charges.
An investigation was initiated due to complaints from witnesses, with a focus on "actions contrary to public decency" that could result in administrative penalties.
Elisabetta Pesce, Venice's councilor for public security, criticized the couple's conduct, citing a lack of respect for the city.
This incident comes after the couple was permanently banned from Venezia Turismo Motoscafi, the boat company involved.
Kanye West had previously drawn attention for exposing his bare buttocks while on a river taxi in Venice.
If the prosecutor decides to proceed, potential charges may lead to notifications sent through the relevant embassies.
Venice takes breaches of public decency seriously, with the possibility of severe punishments.
