Huntsville terrorism suspect Aziz Sayyed did not plan on conducting a suicide bombing, instead he wanted to live and carry out additional attacks for which ISIS would claim credit, an investigator testified today.

Sayyed, a 22-year-old college student, is accused of obtaining bomb making materials to set off an explosion at a Madison County police or military building. His case is headed to a grand jury for consideration of an indictment. During a preliminary hearing Tuesday afternoon, Madison County District Judge Schuyler Richardson ruled there is probable cause for the charge against Sayyed.

Sayyed first came under investigation by the FBI in January when someone reported he had been making some statements involving ISIS, Huntsville police Investigator Brad Snipes testified. Snipes was being questioned by Madison County Assistant District Attorney Jay Town.

In April, Sayyed got a sheet of plywood that he said he would use to practice his knife-handling skills, according to authorities. Snipes told Judge Richardson Sayyed wanted to behead "infidels and Muslims not following the proper path."

Sayyed was arrested June 15 by Huntsville police in a traffic stop downtown. That day, police seized from his home at Twickenham Village Apartments the materials needed to make a TATP (triacetone triperoxide) bomb. The TATP bomb is the kind that was used at an Ariana Grande concert in Manchester, as well as in other bombings in Paris and London. More than 20 people were killed and dozens injured in the concert bombing.

Snipes testified the materials for a TATP bomb include acetone, sulfuric acid, hydrogen peroxide and a cooler, according to Sayyed. Also seized from Sayyed's apartment were a computer, plywood and numerous throwing knives, a passport, Iranian money and receipts from his purchase of bomb-making materials, the investigator testified.

The day of his arrest Sayyed also was interviewed by FBI agents for about four hours.

"So in this interview, he admits to knowing how to build a bomb, he admits to having all the precursors to build a bomb, he admits to having desire to build a bomb (and) that he had talked to people about targets here in Madison County?" Town asked the investigator.

"That's correct," Snipes responded.

Two months before his arrest, Sayyed showed his friend an ISIS flag and watched ISIS videos that depicted beheadings and other violence, Snipes told the judge.

Just days before his arrest, Sayyed, who was being followed by investigators, went to Walmart on University Drive and purchased acetone on June 4, Snipes testified. Later that week, Sayyed returned to the store to buy hydrogen peroxide, according to testimony. Snipes testified that on June 9, Sayyed told a friend he was "trying to make something" with a cooler at his house.

Under cross examination by defense attorney Bruce Gardner, Snipes told the judge police did not find any evidence that Sayyed had already started the process of making the bomb.

Snipes testified that Sayyed said the bomb, which would take about six hours to build, could take out half of a restaurant.

Before his arrest Sayyed also told a friend his targets would be noncivilian, such as police of military buildings in Madison County, the investigator testified. Snipes told the judge police used confidential informants to obtain recordings of Sayyed pledging allegiance to ISIS and discussing his bombing plans.

Sayyed is charged with second-degree soliciting or providing support for terrorism and held without bail. Judge Richardson has said he intends to set bail in the case, but he did not make a ruling at the end of Tuesday's hearing. He is expected to issue a written ruling.

The charge is a Class C felony, which carries a recommended bond amount of $2,500-$15,000. But, judges have discretion in setting bond. They can consider things like criminal history, background, character, age and the nature of the alleged crime.

Prosecutors are asking the judge to require Sayyed be on house arrest and wear an ankle monitor. Town said the state wants a bail of at least $150,000 cash.

Town has argued that Sayyed should be denied bond because "he is an absolute threat to the public."

Gardner has said Sayyed is "illegally" and "unconstitutionally" detained in the Madison County Jail. Gardner has asked that Judge Schuyler Richardson either release Sayyed or set a bail amount that is within the recommended range for a Class C felony.

Sayyed's case will be presented to a grand jury, which will be asked to decide whether prosecutors have enough evidence to send the case to trial.
