MENOMINEE, Mich. (AP) -

A western Upper Peninsula man is jailed after authorities found several explosive devices in a Menominee apartment building.

Menominee County prosecutor Dan Hass tells the Eagle-Herald of Marinette, Wis., that the 51-year-old man could be charged Saturday and arraigned as early as Monday.

At least five devices were found by police Friday afternoon after a search of the man's apartment. Neighbors in the 8-unit building were notified, but an evacuation was not ordered.

A bomb squad was called in late Friday night.

Police were notified Thursday of threats apparently made to the man's wife.
