A UPS delivery driver was robbed at gunpoint Wednesday night on Chicago's South Side.

Police say two men approached and then robbed the driver just before 9 p.m. in the 8500 block of South Prairie. The thieves showed a gun and then grabbed at least three packages out of the back of the truck before they got away, according to UPS.

The driver was not injured in the incident.

A day earlier, a FedEx truck was stolen in Chicago, authorities said. Police said the truck was stolen around 11:30 a.m. Wednesday near 74th and Vernon, just days after some of the biggest holiday sales led to an online shopping frenzy across the nation,

It was later located about a half-mile away in the 7400 block of South Evans.

Authorities initially said several stolen FedEx packages were recovered and victims were being interviewed Wednesday afternoon. They later said it has not yet been determined if any packages were taken from the truck.
