Rochester N.Y. -The U.S. Postal Service is offering a reward of up to $50,000 for information solving the carjacking of a Postal Service van in Rochester.

It happened late Saturday morning near the railroad tracks near 693 Ridgeway Avenue.

Investigators say three people in a tan-gold vehicle stopped in front of the van, one person got out and ordered the driver out of the van at gunpoint. Both vehicles left, and the van was later found in the 800 block of Flower City Park.

Authorites reported previously that a package was missing from the van.
