Several buildings in Hayes Valley were evacuated Thursday after a resident said he ordered a cooking mold from eBay but was instead mailed an old-school bomb, police said.
The package arrived at the residence in the 400 block of Linden Street around 2 p.m. Inside the package was a “vintage” 40 millimeter antiaircraft mortar projectile, police spokesman Lt. Troy Dangerfield said Friday.
Cops arrived around 5:18 p.m., Dangerfield said. They evacuated the building, as well as surrounding buildings, while a police bomb squad took possession of the device, he said.
Inspectors from the U.S. Postal Service have been notified, and they will take on the investigation, Dangerfield said.
It was not immediately clear whether the device was in danger of detonating.
In Concord on Thursday, explosive teams from Travis Air Force base carefully removed four Word War II-era mortars from a home around 9 p.m., according to KTVU Channel 2 News.
Ten homes were evacuated, according to the report. The bombs were also deemed not in danger of detonating.
Both incidents are under investigation.
