Tuscaloosa police had arrested Williams on Monday and charged him with carrying a gun without a permit, according to the Sherriff's Office.

Three of the players players were reserves on Alabama's 2012 BCS national championship while Williams did nit play during the 2012 season. SB Nation noted that the players were top recruits for coach Nick Saban.

An Alabama spokesman told USA Today that the school is aware of the arrests but had no immediate comment.

Williams later used that victim's student debit card and credit card to purchase snacks from a vending machine in a dormitory, according to al.com's reporting on the arrest warrants.

Al.com said the arrest warrants allege that Calloway later used the second victim's student debit card with knowledge it was stolen.
