NEWARK, Ohio (AP) _ An Ohio man who police say had a collection of explosives when he was arrested has pleaded guilty to a count of unlawful possession of a dangerous ordnance.  

The Columbus Dispatch reports (http://bit.ly/1LqOimo) 30-year-old Jay West was sentenced Thursday to 30 days in jail and three years' probation.

Police say they found five 1.25-pound blocks of C4 explosives and accessories to detonate the materials when they searched the Newark man's home Aug 3.

Prosecutors say the materials were military explosives that appeared to have made their way to Ohio from a West Coast military facility.

An investigation showed that West purchased the materials from a Mount Vernon man and that it seemed to be a “spur-of-the-moment” transaction.

West's attorney declined to comment.
