(USA Today) -- Justin Bieber is in trouble - again.
The pop star was arrested early Thursday for drag racing and DUI in Miami Beach, police tell NBC 6 South Florida.
Bieber, 19, was in a rented Lamborghini.
The bad boy's entourage had apparently used their cars to block traffic on Pine Tree Drive at 26th Street, says the Miami Herald, to create a drag strip for the star.
According to Miami Beach Police Sgt. Bobby Hernandez, the incident happened about 4 a.m.. "He was pulled over and failed a field sobriety test," Hernandez told the Orlando Sun-Sentinel.
TMZ reports that Bieber is in custody and is at the police department where he is being tested, presumably to more precisely measure his blood alcohol level.
His next stop will likely be Miami-Dade County's Main Jail, where he will be booked and processed and bail will be set.
The Opa-locka Police Department is also investigating an unauthorized escort of Bieber, a police spokesman told NBC 6 on Wednesday.
"We know it was an unauthorized detail," Assistant City Manger David Chiverton confirmed to the Herald. "We are trying to determine where the authorization for the officers to escort Mr. Bieber came from, where he was escorted and how many of our officers were involved."
Bieber has been spotted in different places in the Miami area in the past few days, and has been posting videos and photos of himself smoking a cigar, skateboarding at Lil Wayne's Miami Skate Park, seeing the sun rise, and noting all the paparazzi aimed at him on the beach.
E! reports he spent some time with his dad, Jeremy Bieber. And on Monday, the singer and pals hit Mansion nightclub before heading to King of Diamonds strip club.
