A grand jury has handed down five charges against the Ocala man accused of plotting to blow up Target stores to lower the company's stock.

The indictment against Mark Charles Barnett was filed in U.S. District Court in the Middle District of Florida on Wednesday.

The counts include a charge of attempting to damage or destroy by means of fire and explosives property that belonged to Target and possession of a firearm by a convicted felon.

In a criminal complaint filed in February, Barnett is accused of offering $10,000 to a confidential source to "deliver packages" to multiple locations, including Florida, New York and Virginia. Prosecutors say he created at least 10 explosive devices and disguised them in food packaging.

Barnett wanted Target's stock to fall so he could buy cheap shares, investigators say.
