Law enforcement will increase security at LSU home games starting this weekend, particularly targeting underage drinking after recent incidents involving alcohol on campus, including the death of fraternity pledge Maxwell Gruver last week.

East Baton Rouge District Attorney Hillar Moore III sent an email to local high school administrators on Tuesday about the plans additional security. His email references the recent arrest of a man with a cast on his arm who was captured on video beating up another person while tailgating before the home game last Saturday. 

"Although the recent publicized arrest did not involve an area high school student, the police advise that possession of alcohol and intoxication of high school students on campus is an increasing issue," Moore wrote. "All of the law enforcement agencies that provide security to LSU on LSU game days will increase their presence and will not tolerate any such activities."

Moore said law enforcement addressed similar concerns last year but Gruver's death — which university officials have called a possible hazing incident — has "added to the heightened need."

Preliminary autopsy results showed Gruver sustained a highly elevated blood alcohol content. 

"(We) hate to see young kids screw up their education and have a record," Hillar wrote in an email Thursday.

"Neither LSU nor any other law enforcement agency working the LSU games wants to arrest, issue summonses or take any legal action against these students," Moore told school administrators.

"We hope that by all of us working together (administrators, parents, students) we can avoid law enforcement involvement with our youth on the LSU campus."

In the wake of Gruver's death, LSU officials have implemented an indefinite ban on Greek activities.

Tailgating as a Greek organization is prohibited this weekend when LSU plays Syracuse at home Saturday, which means fraternities and sororities may not gather in groups of 10 or more.

Other prohibited activities include "common source alcohol, food, chapter tent, chapter house, uniformed attire, presetting of space (and) providing alcohol to others."

Ernie Ballard III, an LSU spokesman, said in an email that LSU police and supporting law enforcement agencies associated with LSU game days "remain vigilant and committed to the safety and security of the LSU community and all who want to share in the game day experience.

He said educating the community about potential safety concerns is a shared responsibility.
