MIAMI (CBSMiami) – A southwest Miami-Dade man who reportedly threatened to kill his boss and co-workers while dressed up like the Joker from the ‘Batman’ movie appeared before a judge over the weekend.

Enrique Dominguez, 20, was arrested Friday and charged with aggravated assault. On Saturday he was arraigned and bond was set at $5,000. While Dominguez was given ankle monitor house arrest and bond, the Department of Corrections says there is a “magistrate hold” on him and no bond has been set for that. The DOC said he will remain jailed at least until a February 22nd hearing before the judge who has been assigned the case.

During questioning, Dominguez allegedly confessed that he had sworn his “allegiance to Allah” and bought a shotgun so he could kill his co-workers at J&B Importers, a company in Southwest Miami-Dade that distributes bicycle parts. A search of Dominguez’s residence turned up a clown mask, duct tape, plastic wrap, gloves and two large knives, according to police.

The Miami-Dade police department’s Homeland Security Bureau said they had received reports that Dominguez had “expressed an intent to become radicalized” and openly discussed a plot to kill his supervisor, according to his arrest report.

A co-worker reportedly told investigators that Dominguez had said he had bought a shotgun to kill his boss and then showed off execution videos posted by ISIS.

Detectives found social-media photos of Dominguez “dressed as clown” while posing with a large knife, according to his arrest report. In one photo, he posed with a display of 15 combat-style knives – the caption read “My lil arsenal.”

But fellow employee William Moreira said he never heard Dominguez talking about killing anybody.

“He’s a young guy. It was stupid. I don’t think he was going to do it,” Moreira said.

During Dominguez’s bond court appearance his attorney, Saam Zangeneh, downplayed the threats.

Zangeneh said Dominguez was harmless, a young man who may have “stepped over a line” but posed no threat.

“This man’s done an Internet lashing out,” the attorney said.”When you get frustrated you post something on the Internet that’s not real. I see it all the time.”

But Judge Gloria Gonzalez-Meyer didn’t buy it and ruled there was probable cause for the assault charge.

Zangeneh recently defended Derek Medina, the man dubbed the “Facebook Killer.” In November, 2015 , jury found Medina, 33, guilty of second degree murder in the 2013 shooting death of his wife Jennifer Alfonso. Afterward, Medina posted pictures of her body on Facebook. His sentencing is set for February 5th.
