A Federal Aviation Administration employee is under investigation after flying from Atlanta to New York with a gun in his carry-on.

Transportation Security Administration officials said in a statement Friday that the Atlanta-based FAA safety inspector was arrested at LaGuardia Airport after a gun was found during a security check.

Authorities say the employee on Tuesday used a badge to gain access to a secure area of Hartsfield-Jackson International Airport and bypassed TSA screening. FAA spokeswoman Kathleen Bergen said in a statement that the agency has ordered the suspension of the program allowing safety inspectors to bypass security screening.

The arrest comes less than a month after investigators uncovered a gun-smuggling scheme involving current and former airline employees and planes flying from Atlanta to New York. Authorities pledged stricter employee screening after the operation was uncovered.
