A Florida man who allegedly confessed to pledging “allegiance to Allah” and plotting a mass shooting while dressed like a comic-book villain will only need to post $5,000 bond and stay on house arrest as he awaits trial.

Enrique Dominguez, 20, was arrested Friday and charged with aggravated assault, the Miami Herald reported.

Earlier this month, Dominguez allegedly told a co-worker at bicycle part distributor J&B Importers that he’d purchased a shotgun to murder his boss. He then showed the co-worker ISIS execution videos, according to an arrest report reviewed by the Herald.

Dominguez “expressed an intent to become radicalized” and said he would “dress up as the Joker from the Batman movie and bring the gun to work during my break,” the report said. Dominguez has a Joker tattoo on his shoulder, the arrest report stated, and has posted photos dressed as a clown on social media sites. One allegedly shows him posing with 15 knives. The caption for that photo reads “My lil arsenal.”

Investigators said they found a bag with a clown mask, duct tape, plastic wrap, gloves and two large knives when they searched Dominguez’s home. He allegedly confessed to planning a killing spree following a “day of allegiance.”

Dominguez’s attorney, Saam Zangeneh, said in court on Saturday that the charges had been overstated.

“This may have been some Internet lashing out when you get frustrated with someone and you post things on the Internet,” he said.

The allegations against Dominguez are reminiscent of the deadly 2012 theatre massacre in Aurora, Colorado. During that attack, James Holmes dyed his hair orange before opening fire on a crowd watching a Batman film, killing 12 and wounding 70. He reportedly later told police he was “the Joker.” Holmes was sentenced to 12 consecutive life sentences in August.
