A wealthy New Jersey suburb that is home to the state's new governor-elect has been upended by the arrest of two teenage terror suspects, as details emerged about their alleged plans.

Milo Sedarat and Tomas Kaan Jimenez-Guzel, both 19, were taken into custody on Wednesday, after the FBI uncovered a plot to bomb gay bars in Detroit in an ISIS-inspired attack on Halloween.

The alleged scheme was uncovered last week by the FBI and the NYPD's Intelligence Bureau, which said the bombing was intended to copy ISIS's terror attack in Paris in 2015. 

Sedarat was then apprehended at his family's three-story home in tony Montclair, New Jersey, which is valued at $1.2 million, according to the New York Post. 

The sight shocked neighbors, who described seeing nearly two dozen law enforcement vehicles pulling up to arrest the suspect.

At least some were armored, and one neighbor told Montclair Local he saw law enforcement officers carrying automatic rifles around 11am.

Meanwhile, Jimenez-Guzel was apprehended in a food court in Newark Liberty International Airport on his way to Turkey, with the goal of reaching Syria to train with ISIS, federal authorities say.

He was allegedly intending to travel on November 17, but moved his flight forward after hearing that the FBI had raided the homes of several other terror suspects in Detroit, sources said. 

The alleged homegrown-terrorists had come from well-off families.

Sedarat's father is famed Iranian-American poet Roger Sedarat, and Jimenez-Guzel's mother, Meral Guzel, serves as the head of the United Nation's Women's Entrepreneurship program.

She has been with the United Nations for more than a decade, working on female empowerment after previously working in the finance sector, according to her LinkedIn.

Both Sedarat and Jimenez-Guzel were also student athletes at their local high school.

At six-foot-one and 235 pounds, Jimenez-Guzel served as a defensive end on the football team, while Sedarat was on the wrestling team.

'They're good kids,' one woman told the New York Post, while others described the Sedarats as 'good neighbors' and a 'good family.' 

But authorities say Sedarat and Jimenez-Guzel were secretly in a group chat alongside fellow alleged terrorist suspect Saed Ali Mirreh, also 19, of Kent, Washington.

'In their communications, they discussed detailed travel plans, physical training, weapons - including firearms and IEDs - and methods to avoid law enforcement detection,' Acting US Attorney for the District of New Jersey Alina Habba said as she announced the charges against the teenagers.

She said the messages also included photographs of Jimenez-Guzel standing in front of an ISIS flag holding a knife, as well as statements he made about conducting a 'Boston bombing-like attack.'

 Disturbing court documents obtained by the New York Post describe how the teenagers said they wanted to behead infidels and become famous for ISIS-inspired terror attacks.

They also allegedly fantasized about executing Jews and carrying out antisemitic attacks in the tony New York City suburb.

In one excerpt from the criminal complaint, authorities described how Sedarat raged about his mother having Jewish friends and saying he wanted to execute '500 Jews' and make their wives and children slaves.

He also allegedly said he wanted to use his car to mow down a pro-Israel march in Montclair.

Jimenez-Guzel, meanwhile, allegedly demonstrated an eagerness to participate in terrorist activities.

In one video call referenced in the complaint, Mirreh said they would have to be prepared to slit people's throats if the were forced to make any propaganda videos.

Jimenez-Guzel then volunteered to do the beheadings himself, saying: 'I'll do it, bro.'

In another group chat, the teenager allegedly mused about craving infamy and said he wanted the group to 'do something that's going to leave a mark in history.

'Something that's gonna make them create a documentary on you on Netflix. Something that's gonna make you have a Wikipedia page.'

Other times, prosecutors say, Jimenez-Guzel boasted he would wind up being 'one of the most 100 evil people in the world,' and posted a document in Arabic on social media titled in English 'KILL THEM SILENTLY.'

It encouraged Muslims to practice the 'obligation' of jihad and 'terrorize the disbelievers to avenge their Muslim brothers.' 

When Mirreh noted in a group chat they would have to 'unalive' somebody 'to get that mentality and get into our brain that we unalive someone and once we come, we don't hesitate no more,' Jimenez-Guzel responded: 'Bro, it'll be easy for me.'

The group's alleged actions plans were reportedly uncovered when an NYPD undercover officer was monitoring a suspect who was in communication with terror suspects arrested in Michigan, ABC 7 reports. 

In that case, three additional Michigan men were charged with intending to supply weapons for an alleged ISIS-inspired attack at a gay bar in Michigan.

Jimenez-Guzel is now charged with attempting to provide material support to a foreign terror group, and Sedarat was charged with two counts of transmitting threats to interstate and foreign commerce.

They were both shackled as they appeared in court on Wednesday, when a judge barred them from having contact with their alleged co-conspirators.

If convicted, they could now face 20 years in prison per count, plus a $250,000 fine and a lifetime supervised release.
