Authorities have arrested 99 people in what they say is the biggest drug bust in the city’s history.

A two-month undercover operation centered on the University of Alabama campus netted 61 UA students and others who face 183 charges.

Seventy-four people were arrested in a massive sweep that began at 4 a.m. Tuesday. The other 25 were arrested earlier this year.

Confidential informants helped investigators with the West Alabama Narcotics Task Force, said Tuscaloosa Police Chief Steve Anderson.

The vast majority of arrests involved the sale or possession of marijuana.

“I know a lot of people consider it to be a harmless drug,” Anderson said. “It’s still illegal to possess it, distribute and traffic it in the state of Alabama. Therefore, it’s against the law and we’re going to enforce the law no matter how harmless people think it is.”

Small amounts of cocaine, LSD, prescription pills and ecstasy were also bought and sold. Officers seized three guns and thousands of dollars during their round-up of arrests Tuesday.

“We want to send a clear message that it’s not going to be tolerated and if we discover who you are, we are going to come after you,” Anderson said. “We realize that we do have an issue of drugs in our community and our task force is dedicated to doing as much as they can to eradicate the drug problem in the city of Tuscaloosa and throughout Tuscaloosa County.”

According to jail logs, most were between 18 and 20 years old and lived on or near the University of Alabama campus.

The UA students who were arrested will be referred to Judicial Affairs, said university spokeswoman Cathy Andreen.

“Once judicial reviews are completed, students will receive sanctions up to and including expulsion,” she said.

Dr. Judy Bonner sent an e-mail to faculty, staff and students Tuesday.

“UA has a zero tolerance policy when it comes to the sale or distribution of drugs, on or off campus, and we will continue to vigorously enforce that policy,” she wrote.

“These students represent a small group of UA students. UA will review our current policies and practices to ensure that we are doing all we can to educate students to make the best decisions they can and that we are providing an environment that is conducive to learning,” she wrote. “Students must understand that they have a choice when it comes to their behavior, and that their decision to violate drug laws and the Student Code of Conduct will have consequences.”

Anderson said that the confidential informants made buys at different areas on campus, including residence halls. He credited the scope and success of the operation of the new WANTF commander, Capt. Wayne Robertson.

“This shows the dedication of the new leadership in that unit,” he said. “He’s very bold, he’s aggressive and he knows what the problems we are facing in our community.”
