San Bernardino police officials inspected a package at a Southern California UPS facility early Saturday morning after a driver recognized the address on the package was that of the suspected San Bernardino shooters.

The county sheriff’s department bomb squad was able to determine that the item “posed no threat,” after inspecting the package at the facility, San Bernardino Police Chief Jarrod Burguan tweeted.

Burguan said the package was shipped from a “reputable vendor,” but authorities had isolated it to be safe.

A UPS driver had left the shipping facility to make deliveries, but later returned after realizing the address on a package was the Redlands, California, home of Syed Rizwan Farook and wife Tashfeed Malik, accused of killing 14 people and injuring 21 others Wednesday at a holiday party at San Bernardino’s Inland Regional Center.

UPS temporarily suspended operations at its San Bernardino facility while the investigation took place, UPS spokesman Dan Cardillo said in a statement.
