A uniformed TSA agent lured a college student into a La Guardia Airport men’s room under the pretense she needed more screening — and then he molested the woman, sources told The Post on Friday.

Shortly after the attack, suspect Maxi Oquendo allegedly pretended to pore over surveillance video looking for the perp, but he was identified by witnesses and arrested.

“He was the evening supervisor. He was one of the guys going over the TSA videos,” one source said.

The sick attack happened right after the 22-year-old victim, from South Korea, got off a Southwest Airlines flight from Salt Lake City at about 8 p.m. Tuesday in Terminal B and was allegedly approached by ­Oquendo, 40.

The agent told her to follow him so she could be searched to see if she was carrying a knife or a weapon, sources said.

The unsuspecting woman followed him up an escalator to the third floor, where he directed her into the bathroom, the sources said.

Once inside, he molested the victim after asking her to lift her shirt and unzip her pants, the sources said.

He then allegedly led her outside and she reported the incident to other TSA officials and Port Authority cops.

Oquendo was working as a TSA evening supervisor that night. After learning that a sex complaint had been filed, he went through the motions of reviewing video surveillance footage, sources said.

But two female witnesses who work at the airport were able to help provide a description that matched the heavyset Oquendo, sources said.

The victim then pointed Oquendo out to police.

He was arrested Thursday evening and charged with sex abuse, forcible touching, unlawful imprisonment and official misconduct.

“This guy is real predator,” a sickened law-enforcement official said.

“She came here from Utah to do the tourist thing in New York City and this happened to her.”

TSA Administrator Peter V. Neffenger said the agency has fired Oquendo.

“We expect our employees to conduct themselves with integrity, professionalism and respect,” he said.

Oquendo was still awaiting arraignment late Friday, said a spokeswoman for Queens DA Richard Brown.
