LSU running back Lanard Fournette was arrested and booked into East Baton Rouge Parish Prison after the 20-year-old was allegedly caught gambling with a false ID at the L'Auberge Casino in Baton Rouge, according to state police. 

Fournette, the younger brother of former LSU standout Leonard Fournette, was arrested Monday after surveillance video showed and casino personnel confirmed he gained access to the gaming floor Saturday with a different ID than his own driver's license, according to his arrest report.

"Coach Ed Orgeron is aware of the incident," LSU team spokesman Michael Bonnette told The Advocate. "He will be disciplined internally." 

Security video showed Fournette playing at a “craps table” for 16 minutes around 1:30 p.m., before walking to the player’s services counter. Fournette then allegedly presented his real ID to the cashier for a cash withdrawal, who determined his accurate age and contacted security, the report says. 

Fournette, of Slidell, was detained at the casino, but left before the officer's arrival, the report says. When casino security asked Fournette about the incident, Fournette said he used another person's ID to enter the casino, the report says.

Fournette is a redshirt sophomore at LSU who's played in just three games. He redshirted as a true freshman in 2015 before playing against Jacksonville State, Missouri and Southern Miss last year. He's one of five scholarship running backs expected on the roster this fall. 

He's the second LSU player to be arrested this spring, joining offensive lineman Adrian Magee. Magee was arrested in April on a count of simple burglary. Magee remains suspended indefinitely, coach Ed Orgeron said last week.

As a first-time offender, the district attorney could potentially offer a pre-trial diversion to Magee, said Brent Stockstill, the attorney representing the player.
