NEW YORK » Federal investigators are searching for three men they say held up an armored truck guard at a Queens bank in broad daylight.

Authorities didn’t disclose how much was taken in the robbery that occurred inside an ATM lobby at around noon Friday at a HSBC bank branch in the Elmhurst neighborhood of Queens.

They say the guard was sprayed with a chemical after making a regularly scheduled pickup at the bank.

Security photos show one of the men wearing all black pointing a handgun in the guard’s face.

Authorities say the men fled in a blue or black Ford Explorer.

Armored truck company GardaWorld has offered a $50,000 reward for information leading to an arrest and conviction in the case.
