Shocking stun-gun lapse at Kennedy

A Greek national was able to slip a stun gun past inept TSA agents at Kennedy Airport yesterday after using it in the alleged rape and assault of his ex-girlfriend in Queens, authorities said.

Prodromos Vasilopoulous was about to board a Virgin Atlantic flight to London when he was picked up by authorities at the gate at around 8 a.m.

He had the stun gun in his Nike carry-on bag, and had no trouble getting it past the security checkpoint, sources said.

Vasilopoulous, 23, had purchased the weapon in London.

“He did get through [Transportation Security Administration] screening without that stun gun being detected, which was allegedly used in the crime,” said a law-enforcement source.

“This is another major TSA failure, and, in this particular case, they cleared an alleged [criminal] to get on an international flight with a weapon.”

The 19-year-old victim told detectives that Vasilopoulous posed as a UPS deliveryman and stunned her when she opened the door, authorities said.

He allegedly beat and raped her for several hours — at one point smothering her with a pillow and forcing her to take 35 Advil, the sources said.

“He tortured her,” said one law-enforcement source.
