Package containing battery explodes at FedEx office

A package containing a lithium battery exploded at a Federal Express office in Sorrento Valley early Wednesday, but no one was hurt, police said.

The office at 9999 Olson Drive was evacuated after the roughly 6:10 a.m. explosion, San Diego police Officer Dan McClain said.

McClain said it didn’t appear to be a big blast.

Traffic was also rerouted while the incident was investigated.
