Guards in armored truck heist being investigated after failing polygraphs

The two armored truck guards in yesterday’s brazen $450,000 daylight heist in Brooklyn both failed lie-detector tests – and now some investigators believe they were in cahoots with the armed robber, law enforcement sources told the Post.

“The driver and courier failed the polygraph miserably,” said a law-enforcement source.

“Some of the questions were, ‘Did you steal the money?’ Failed. ‘Did you plan to steal the money?’ Failed. ‘Did you know the money was going to be stolen?’ Failed. The only question they got right was, ‘What’s your name?’”

The robbery took place in Canarsie at about 10:30 a.m.

The driver told investigators he let the gunman into the truck after mistaking him for the courier and that the gunman held a gun to his neck, then fled with a white duffel bag packed with the cash.

“The driver said he thought it was the courier and accidentally hit the button letting in the perp,” a law-enforcement source said.

The driver and courier agreed to take the FBI polygraph test they failed, the sources said.

Another reason the FBI doesn’t believe the dim duo’s tale is that video surveillance shows the gunman and the courier were dressed completely differently and the side windows of the truck are easy to see through – casting doubt on the driver’s claim he mistook the two, the sources said.

The driver and the courier have not been charged.

The results of polygraph tests are not admissible in court but are used by investigators to gather information.
