The student who was seen on the Texas A&M campus nearly two weeks ago carrying a replica AK-47 borrowed the weapon for a Halloween costume, according to a report released Tuesday. (See a photo of the replica here.)

The campus was locked down Oct. 28 from 3:30 p.m., when a Code Maroon was issued, until just before 6 p.m. after a bus driver reported seeing a man with what appeared to be an AK-47 assault rifle near Rudder Tower.

Three students, including the bus driver, filled out voluntary statements that were included in the police report, detailing what they saw that day.

The Eagle filed an open records request for the police report last week.

University police and others investigated the reports and discovered it was a student carrying a hard plastic replica rifle through Rudder Tower on his way to a parking lot in the West Campus area.

According to the report, a gunnery sergeant who works in the Trigon allowed a 28-year-old Marine to check out the weapon for use during a Halloween party.

The student is listed in the campus directory as a sophomore anthropology major.

The sergeant who allowed the gun to be checked out called police as soon as he learned of the Code Maroon warning.

Police had located the Marine and the replica weapon within hours, and no criminal charges were filed. It was unclear late Tuesday if the student faced any disciplinary action as the result of any code of conduct violations.

It also was unclear if any action was taken against the gunnery sergeant who agreed to loan the student the fake gun.
