The arrest came after a collaborative investigation among law enforcement and the District Attorney. Alamance Co. authorities say they've put extensive hours into monitoring social media.

'We will not tolerate destruction of property or harming of others," Johnson said.

District Attorney Pat Nadolski says Jeffries is charged with inciting a riot.

"This is a significant case because it's a public safety issue," said Nadolski. "We are going to work with the law enforcement to make sure these types of threats are not carried out."

Johnson says his department has a zero tolerance policy for anyone making threats.

"We at the Alamance County sheriffs office are not and will not take either side on the issue of the confederate monument or anything else around that issue," said Johnson. "We are prepared! We are protecting the courthouse and that's all I will say."

According to Nadolski, Jeffries has a "significant" criminal record including assault and armed robbery.

Jeffries is being held in jail under a $20,000 bond.

Deputies are also looking for the person who made the comment about tearing the confederate statue down.
