A bomb threat shut down Ford Motor Co.’s Romeo Engine Plant Thursday morning and workers were sent home as a precaution, a Ford spokesman said.

Afternoon-shift workers should come in unless the company notifies them otherwise, Ford spokesman Mike Moran said, according to the Detroit News.

Authorities are searching the more than 2 million-square-foot plant, Moran said. The Macomb County Sheriff’s Office brought in bomb-sniffing dogs.
