Bomb squad detonates grenades found in Palo Alto home

Box of grenades buried, destroyed in a Webster Street yard

The Santa Clara County Sheriff's Office Bomb Squad on Friday buried and detonated a cache of World War II-era grenades that a Webster Street resident found in a box while cleaning the house, Palo Alto police said.

Officers learned about the discovered stash of explosives at about 3:35 p.m., when they received the call from a resident of the 1900 block of Webster, in Old Palo Alto. The person found a box that included eight grenades and a grenade discharger known as a "knee mortar." The person carried it outside and left it in the driveway, where it remained until police and the bomb squad arrived, police said.

The bomb squad tested the grenades and determined that at least one was still live, police said. They buried all the devices in the front yard of the house, covered them with 40 sandbags and detonated them at 7:17 p.m., police said. It remained unknown how many other grenades were live.

There were no injuries; just a few mild disruptions. Three homes were evacuated while police determined how to proceed. Residents in several adjacent homes were also asked to stay indoors. Webster Street was blocked off to traffic for about four hours, reopening at 7:50 p.m.

The Police Department also live-tweeted the event, just after the grenades were detonated, police announced the news on Twitter: "If you weren't within a few blocks, you likely didn't hear it."

News of the Weird. How does a person not know there are grenades in their basement? Must be more cluttered than our house.

Is this why there is a helicopter hovering overhead Palo Alto?

We get revenue if the helicopters refuel at Palo Alto Airport.

Explosion heard. Police still have street surrounded. Paramedic raced away with lights flashing. Hopefully no one is hurt.

@Alex is that a trick question? Jokes aside, thanks for pointing out the typo! We've fixed it.

And the "font yard"? One more typo to correct. And I wish we could more details in the news -- like the number of the house and the owner on Webster. Long ago and far away, the news didn't choose to protect perpetrators or write articles with no names or real information.

Why would anyone keep live grenades in their home? What a foolish thing to do.

Older houses with basements and attics often have odd things left by previous residents. That house just sold this summer and I'm guessing the final house clear-out uncovered those old souvenirs.

Why move explosives to the driveway instead of just leaving them where they were found?
