Zazi, 24, of Aurora, was in federal court Thursday shortly after an indictment with the new charge was released by the Department of Justice. In light of the new charge, Zazi's case was continued to Friday in order to give his defense team time to review the information.

The Department of Justice says Zazi, "knowingly and intentionally conspired with others to use one or more weapons of mass destruction, specifically explosive bombs and other similar explosive devices, against persons or property within the United States."

Surveillance video of Zazi shopping for beauty supplies to use in construction of the bomb surfaced on Thursday night.

The federal government claims Zazi was committed to detonating an explosive device up until his arrest on Sept. 19. The government says they have direct evidence that Zazi actually purchased the component parts of improvised explosive devices and took "substantial" steps to carry out the plan.

The indictment states Zazi purchased most of the components for making the IED's in Aurora and even practiced making the devices at an Aurora hotel before traveling to New York. The FBI says Zazi was intent on blowing something up until the day he was arrested.

The court paperwork lists several chemicals Zazi and his associates would use to make the explosive "Triacetone Triperoxide" or "TAPT," which is the explosive used in the 2005 London train bombings and intended to be used in the 2001 "shoe bomb" plot by Richard Reid.

The indictment states there are surveillance videos and receipts that Zazi purchased six bottles of "Liquid Developer Clairoxide" from a beauty supply store in Aurora on July 25.

An employee at Beauty Supply Warehouse on 6th Avenue and Potomac in Aurora says he waited on Zazi. When he asked Zazi why he was buying so many beauty supplies, he says Zazi said, "I have a lot of girlfriends."

He says he came back several days in a row to buy beauty products.

The indictment goes on to describe how videos and receipts also show that on Aug. 28 Zazi purchased 12, 32 ounce bottles of "Ms. K Liquid 40 Volume," another hydrogen peroxide-based product from the same store.

Experts say a 40 volume would be twice the amount used in a hair salon.

Records cited by the government in the indictment also show Zazi stayed at a nearby hotel suite in Aurora on both Aug. 28 and again on Sept. 6 through Sept. 7 that was equipped with a stove to practice working with the chemicals.

The indictment says Zazi first got instructions on how to build the explosives while in Pakistan in August 2008. The nine pages of handwritten notes describe how acetone found in nail polish remover and hydrogen peroxide can be mixed together with muriatic acid, a household cleaner found in home improvement stores, to make a bomb.

After staying in the hotel suite on Sept. 6, the indictment says Zazi's notes indicate he learned to heat the chemical components to make them more highly concentrated. The FBI searched the room and found acetone residue in a stove vent.

A week later he headed for New York in a rental car and the FBI soon raided the apartment where he stayed. He then came back to Colorado.

Zazi was originally charged with lying to federal investigators in connection to the terror probe. He voluntarily met with federal investigators for three days prior to his arrest. Zazi's father, Mohammed Wali Zazi, 53, was also arrested on Sept. 19 on the same charge of lying to federal investigators.

Father and son appear in federal court

Both Zazis made initial court appearances on Monday. The judge ruled then that the elder Zazi could be released from custody as soon as his home was set up for electronic monitoring.

On Thursday, Zazi and his father made their second appearance in federal court at 9 a.m. where, prior to the new charges, prosecutors were expected to argue that the younger Zazi should remain in custody. Furthermore, the indictment describes Zazi as a "danger to the community" and says he should remain in custody because the government says he is a flight risk. As previously mentioned, Zazi's case was continued to Friday.

The U.S. Attorney's office says Friday will be a detention hearing.

Spokesman Jeff Dorschner says the government has to prove that Zazi is either a danger to the community or a risk of flight. If the judge rules that he is either or both of those things, he will be ordered detained.

Dorschner also Zazi could be moved to New York to continue the investigation there, but the judge must rule on that.

The government asked the judge in Najibullah Zazi's case to dismiss the Colorado-based lying to investigators charge since the more serious charge was filed in New York.

"The judge is considering our motion to dismiss. If he grants that motion no further charges against Mr. [Najibullah] Zazi will be in Colorado," U.S. Attorney David Gaouette said.

Both Zazis entered the courtroom Thursday in white t-shirts, the elder Zazi wearing headphones for his interpreter. Zazi's father sat at a table closest to the judge with his interpreter and a U.S. public defender.

The courtroom, which was about 80 percent full, seemingly housed no family members of the Zazis.

Najibullah Zazi sat in the courtroom between J. Michael Dowling and Arthur Folsom, the younger Zazi's attorney. Four representatives from the U.S. Attorneys Office were also present.

After reading the entire indictment aloud in court, it was determined that Mohammed Zazi could be released from jail even though his home monitoring had not been set up yet.

As 9Wants to Know reported Wednesday, a notice was found on the Najibullah Zazi's apartment saying he and his family needed to move out by Oct. 3. The notice says that the apartment lease is expiring.

Officials in the case originally planned for an undisclosed location where the elder Zazi could reside. By noon it became clear that the location would not work. As a result, Mohammed Zazi returned to court at 1 p.m. 

During the 1 p.m. court appearance, one officials say the proposed residence had fallen through. He explained that the wife of one of the homeowners became afraid. As a result, an alternative location, which is subject to review by probation, was found.

Officials say probation will look into the new residence Thursday afternoon.

The judge in the case questioned whether or not the second location would lead to the same problems as the first. Officials in the case assured him that the permission of all those residing in the house had been granted.

Mohammed Zazi will have a status conference on Monday at 2:30 and a preliminary hearing is set for Oct. 9 at 1:30 p.m.

Terror investigation launched

Najibullah Zazi became the center of the terror probe in early September after renting a car and driving to New York. He was stopped near New York City on Sept. 10 and investigators say they found bomb-making instructions on the hard drive of his laptop computer in his rental car.

In addition to his trip to New York, authorities believe Najibullah Zazi's actions show he was committed to his plan because of his trips overseas to receive bomb-making instructions, the fact that he conducted extensive research on the Internet regarding components of explosive devices, and that he purchased, on multiple occasions, the components needed to produce TATP [Triacetone Triperoxide] and other explosive devices.

Zazi and his attorney Arthur Folsom have maintained Zazi's innocence since his name surfaced as a target of the FBI and Joint Terrorism Task Force investigation. Zazi also told 9NEWS in his first interview on Sept. 15 he is "not a terrorist" and has not associated with any one associated with al-Qaeda.

The organization that claimed responsibility for 9-11 and other world-wide terror attacks was not mentioned by name in the indictment.
