Justin Bieber risked endangering public safety when he zoomed through a park on a Vespa in Florence, Italy on Monday (06Oct14).
The Baby hitmaker was first pictured cruising through the city's streets without a helmet during his holiday with his father Jeremy.
In later images, he was shown wearing the protective headgear but filming his journey on his cell phone while driving the vehicle through a public park.
Two police officers were later seen chatting to Bieber's entourage, although it is unclear what they discussed.
The singer later appears to have flown to another destination, as he shared a snap of him and his father outside their jet on Instagram.com on Tuesday (07Oct14) and wrote, "Me and pops on a world adventure."
