A Mahoning County Grand Jury has indicted the man accused of threatening to set off explosives at the Mahoning County Courthouse and the U.S District Courthouse in downtown Youngstown. 

Thirty-one-year-old Tyler Graham has been indicted by the grand jury on two counts of terroristic threats, two counts of extortion, one count of inducing panic, one count of telecommunications harassment and one count of disturbing public services. 

Graham is accused of calling Austintown Police Dispatch and stating that four 'detonation devices' had been placed inside of 120 Market Street, the address of the Mahoning County Common Pleas Court. 

The suspect allegedly said that another explosive device had been placed in the "courthouse across the street," but did not specify whether that referred to the U.S. District Courthouse or the Youngstown Municipal Court on Front Street. 

Just after 10 a.m., Graham allegedly made a second call to Austintown Dispatch where he requested a ransom of $100,000, claiming the devices would detonate shortly after the noon hour.

The Mahoning County Sheriff's Office, U.S. Marshals, and the Youngstown Police Department Bomb Squad were dispatched to the courthouses and began searching. The U.S. Department of Homeland Security deployed one of their bomb-sniffing dogs to search the federal courthouse. 

Shortly after 1:30 p.m., officials said the Youngstown Municipal Court Annex building on Front Street had also been cleared. 

According to Sheriff Greene, several detectives are working on the case and are being assisted by the Federal Bureau of Investigations and the ATF.
