A whole lot of presents did not get delivered Monday when an armed robber carjacked a UPS van and unloaded it with an accomplice in East St. Louis.

The UPS delivery driver was making deliveries before 1 p.m. Monday in the 500 block of North 22nd Street when a man wearing a ski mask jumped aboard the van and pointed a gun, East St. Louis Police Chief Michael Floore said. The delivery man was forced to drive to 37th and Caseyville Avenue, where the masked gunman used a cell phone to make a call.

A blue van pulled up. Its driver and the robber unloaded most of the UPS van.

UPS spokeswoman Susan Rosenberg, based at the corporate office in Atlanta, Ga., said the truck was recovered. "They did not get all the packages," she said.

The driver was unharmed.

"He's shaken up by it," she said, noting the UPS management team met with him and made counseling services available to him.

The driver, whose name was not released, was off work Tuesday. Rosenberg said the driver lives in the metro-east, is experienced and has worked for UPS for 25 years.

"He's well acquainted with his route in the area," Rosenberg said.

Illinois State Police are also assisting in the investigation.

Rosenberg advised area residents expecting a package Monday that didn't get delivered, to check tracking information online at www.ups.com or call 1-800-PICK-UPS.

Floore asked anyone with information about the robbery to call East St. Louis Police at (618) 482-6700 or CrimeStoppers at (800) 371-8477.
