This is the best summary I could come up with:

Police in Washington state say an old rusted rocket found in a local man’s garage is an inert nuclear missile.

On Wednesday, a military museum in Ohio called police in the city of Bellevue to report an offer of a rather unusual donation.

Bellevue Police Department spokesman Seth Tyler, told BBC News on Friday that the device was “just basically a gas tank for rocket fuel”.

The man, who does not wish to be identified and is “extremely irritated” by the media coverage, “was not expecting a call from us”, Mr Tyler said, saying it seems the museum did not warn him they would be reporting his donation offer.

Officials never suspected that a nuclear warhead might be present, meaning there was no need for mass evacuations in the city of 150,000 people 10 miles (16km) east of Seattle.

The man told police that the rocket belonged to a neighbour who had died, and was originally purchased from an estate sale.

So, not a nuclear missile at all.

A fuel tank from a missile. Probably didn’t pass certification or was a test object.
