RALEIGH, N.C. (WNCN) — Law enforcement responded to Raleigh-Durham International Airport due to a “safety concern” Tuesday morning, according to RDU officials.

Officials said around 6:20 a.m. an arriving passenger called police and said they saw two individuals with weapons in the parking garage, and RDU law enforcement was informed immediately.

“They had guns. Both parties had guns and they ran off, back towards the stairwell,” one airport policeman relayed by radio. The officer described the pair as wearing red masks and black hoodies.

“There’s two at this time, possibly armed,” he added.

The parking garage was closed while law enforcement searched it and began an investigation.

Officials reopened the parking garage around 8 a.m.

Officials said after the investigation “law enforcement…determined there was no evidence of a threat to airport guests and no evidence of any wrongdoing.”
