Bieber, 19, was also reportedly booked shortly after 4 a.m. for driving under the influence, though it is unclear whether he had been intoxicated or under the influence of a substance.
Just a day earlier, on Wednesday the singer was seen riding a Segway through Miami streets, and hanging out on the beach with Rapper Lil Scrappy and Bieber's father, Jeremy.
He's been in Miami since Monday - when it was reported that the teenage heartthrob spent $75,000 at the strip club King of Diamonds as he helped Lil Scrappy celebrate his 30th birthday.
Authorities in Opa-Locka, Fla. are also investigating the events of his Monday night partying, as it was reported that Bieber and his friends were escorted around by police detail.
The details of Bieber's arrest Thursday are unknown, but the "All That Matters" singer is coming off of a string of questionable antics in recent weeks.
