The suspect also possessed an AR-15 assault-style weapon.
Authorities may have thwarted a plan by 23-year-old Conor Climo to firebomb a Las Vegas synagogue and LGBT bar.
Climo was arrested this past Wednesday and U.S. Magistrate Judge Nancy Koppe ordered him to remain in federal custody until his court hearing scheduled for August 23.
NBC Los Angeles reports that Climo was under surveillance and he had been allegedly talking online with white supremacists and in one instance told an FBI informant that he was “scouting places to attack.”
Investigators searched the suspect's home on a warrant and found propellant, circuit boards and “hand-drawn schematics and component parts of a destructive device.”
In their search, they also discovered an AR-15 assault-style weapon and a bolt-action rifle
Climo is charged with possessing an unregistered firearm in the form of the component parts of a destructive device.
The U.S. attorney’s office said in a statement, “Climo would regularly use derogatory racial, anti-Semitic and homosexual slurs.”
“He discussed attacking a Las Vegas synagogue and making Molotov Cocktails and improvised explosive devices,” they add. “He also discussed conducting surveillance on a bar he believed catered to the LGBTQ community.”
If convicted Climo could face up to 10 years in prison and a $250,000 fine.
