Police received a tip from a caller on December 17th who said a man was making the devices and threatening to harm Muslims.

Richmond police said they can’t elaborate on the threats other than to say that Celli’s actions and statements drew the attention of law enforcement, and were very concerning to officers.

Celli appeared to be a supporter of Presidential candidate Donald Trump.  A post on his Facebook page said he would follow Trump “to the end of the world.”
