Police in Miami Beach say they've arrested noted Lamborghini troublemaker Justin Bieber for driving under the influence and drag racing in a rented Lamborghini early Thursday morning.

There aren't many details as of now but Bieber is assumed to still be in custody. Elsewhere in south Florida, police in Opa-Locka are investigating an unauthorized police escort for the singer.

Bieber's got a rough, questionable history with big-ticket cars, including chroming out a Fisker Karma, actually owning and being seen in public with a leopard print Audi R8 and speeding in a Lambo in Dubai.

UPDATE: Per reports from TMZ and SkyNews, Bieber was "on prescription medication, had smoked marijuana and drunk beer" before leaving a nightclub and hopping behind the wheel of a yellow Gallardo. TMZ also reports that Bieber's camp blocked a street so he could race a rapper in a Ferrari 430 Scuderia Spider.


UPDATE #2: Here's Bieber's mugshot and the full report from the Miami Beach P.D., which indicates that he was also resisting arrest.
