A Louisiana student has been investigated by police after saying a math symbol looks like a gun.

KSEE reports the Allen Parish Sheriff's Office searched the home of a student at Oberlin High School after some classmates interpreted his comments as a possible terrorist threat last week. No weapon or evidence of any threat to was found.

Allen Parish School District Superintendent Michael Doucet told KATC that it was a false rumor that started with a poorly judged joke between two students solving a square root problem in math class.

The math symbol for finding the square root is pictured.

"The students were working together, and a student made a math symbol of a square root sign, which kind of looks like a pistol. And he was helping a weaker student, and the student says, 'Well, that looks like a pistol!' And he just made a comment [like] 'let's just get to work before I shoot you with a pistol," Doucet said.

According to Doucet, the comment then spread throughout the school like gossip, and grew into a rumor that the student was planning to carry out a mass shooting like at a Florida school earlier this month. Police said that it could be interpreted as a threat when taken out of context.

"The student used extremely poor judgment in making the comment," the Allen Parish Sheriff's Office wrote on Facebook. "But in light of the actual circumstances, there was clearly no evidence to support criminal charges."

"He committed no crime. He was the victim of the ole morphing of information [phenomenon]," Allen Parish Sheriff Doug Hebert added in a KATC interview.

The Allen Parish School Board will determine if any disciplinary action is required.

Many school and law enforcement officials are on high alert after Nikolas Cruz, 19, opened fire with an AR-15 assault-style rifle at Marjory Stoneman Douglas High School in Parkland, Fla., last week. Seventeen students and teachers were killed.
