The Federal Bureau of Investigation's continued inquiry on the Pensacola Naval Air Station shooting has led to the discovery of a new report that Second Lieutenant Mohammed Alshamrani had filed a formal complaint against one of his instructors in April. The instructor who was later identified as James Day was accused of humiliating Alshamrani in front of his classmates.

The complaint came after Day asked his meteorology class for questions before they were dismissed. It was then that Day turned to Alshamrani and referred to him as “Porn Stash” as a direct reference to a mustache of a porn actor, according to The New York Times.

The offensive nickname angered Alshamrani considering that Day said it in front of 10 other students.

“I was infuriated as to why he would say that in front of the class,” the Times added, citing a quote from Alshamrani's complaint. “Laughing, he continued to ask, 'What? Have you not seen a porn star before?' After I did not respond, he just let go of the subject.”

Two American students helped Alshamrani file his complaint, The New York Post reported.

After the incident, the second lieutenant reported the instructor to CAE USA. Although they still let Day continue with his work, they “offered” to have him apologize to Alshamrani but the latter refused.

The NY Post added that Alshamrani reported Day for the second time when both were paired for a flight training a week after the “Porn Stash” incident. Alshamrani was given another instructor.

Day's employer, Brian Busey, told the New York Times that they are working with the FBI in their investigation on the shooting but he declined to discuss the incident back in April.

“Appropriate personnel action was taken regarding the incident in question, corrective action was taken, the matter was closed back in April and we have no further comment,” expressed Busey, president of the Delaware Resource Group of Oklahoma.

Amid the controversy, Day declined to comment about the incident.

Meanwhile, Rachel Rojas, a special agent in charge of the FBI's Jacksonville office, said that investigators are still looking for leads that could have motivated Alshamrani to do the crime. As for the classroom incident, they find no connection that would link it to the shooting especially because it didn't happen “until more than seven months later.”
