An antique artillery shell led police to evacuate buildings in the Mission district Wednesday morning, after someone left the item at a Salvation Army donation site.
The bomb squad was called to the site at 1500 Valencia St. about 10:30 a.m., Officer Albie Esparza said. Police cleared nearby streets and evacuated buildings as a precaution.
“We determined it to be some sort of ordnance,” Esparza said. “We don’t know the era.”
Esparza said the bomb squad took the shell to a deserted area near Ocean Beach to “render it safe.” Authorities temporarily closed Great Highway from Lincoln to Sloat while the weapon was disarmed.
Such incidents are not uncommon, Esparza said.
“People clean out their garages and find their grandfather’s World War II ordnance, they call the bomb squad,” he said.
