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. Under terms of his release, Dominguez will be on house arrest until his trial.

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.”

During Dominguez’s bond court appearance his attorney, Saam Zangeneh, downplayed the threats and said he was just lashing out on the internet.

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