300 iPhone Xs stolen from delivery truck at San Francisco mall

The devices were stolen from a parked UPS truck, police said.

The phones were stolen from a parked UPS truck, police said. The driver told police that he had parked and locked his truck while he went to make a delivery but returned to find the truck damaged and with the door open.

The truck had been parked at the mall's loading dock, police told ABC News. They believe a white Dodge van was used in the robbery and that the suspect were wearing hoodies.

An inventory check revealed that the packages containing the 300 iPhone Xs, which retail for at least $999 each, had been opened, police said.

It appears that the suspects knew what they were looking for in the truck, police said.

Police are looking for information on the suspects.
