Hantz, the younger brother of Survivor villain Russell Hantz, was reportedly arrested at 2:07 AM by the Lafayette City Police Department.
According to the police, Hantz was arrested after officers responded to a call about a fight in a parking lot near several bars and discovered a large crowd but no fight.
As they attempted to disperse the crowd and clear the area, officers then reportedly spotted a lone yellow 2012 Chevrolet Camaro driven by Hantz driving in the wrong direction and heading toward the rear of the parking lot.
Hantz reportedly attempted to run out of the vehicle when police began to approach his Camaro, but was apprehended after a "very short pursuit" and arrested on suspicion of drunk driving.
The former Big Brother houseguest refused a breathalyzer and a blood test to determine whether he was over the legal limit and is currently still in custody, according to TMZ.
Hantz, a 34-year-old tankerman from Vinton, LA who currently resides in Dayton, TX, was removed from the Big Brother house after an incident in which he appeared to chest thump and shove fellow houseguest Joe Arvin last Friday (due to Big Brother's broadcast schedule, the footage only aired as part of Sunday night's episode).
"As you all know, violence is not tolerated in the Big Brother house, so Willie has been removed from the game," Big Brother executive producer Allison Grodner told the remaining houseguests after the house's speaker system after Hantz was expelled.
