As the would-be Times Square bomber remains in custody and continues to cooperate with authorities, new video released Thursday shows the steps he took to plan what could have been a deadly attack. NY1's Tetiana Anderson filed the following report.

Newly-released surveillance footage shows Faisal Shahzad's SUV pulling into the parking lot of the Phantom Fireworks showroom in Mattamores, Pennsylvania on March 8. It is a chilling glimpse at the would-be bomber's plan, showing the lead up to what could have been a deadly attack in Times Square last weekend.

Watch the complete surveillance footage.

In the footage, Shahzad is seen walking through the door, with another customer close behind. He stops at the counter and appears to talk with the clerk possibly showing some sort of ID or document, then he proceeds into the store to look for explosives. Later, Shahzad walks up to the checkout counter with a basket. It looks as if he goes back into the aisles to gathering a few more items before stepping back up to the checkout. Then he and a clerk appear to lay the merchandise on the counter, among the items he purchased M-88 fireworks, later found in his Pathfinder in Times Square and his Connecticut apartment. Shahzad eventually gathers his bags and the next thing the video shows is him driving off in an SUV.

Days after Shahzad's arrest officials say he has confessed, waived his rights to a lawyer and is still talking -- something investigators say they want want to keep it that way.

"Shahzad has provided useful information and we will continue to pursue a number of leads as we gather intelligence related to this attempted attack," said U.S. Attorney General Eric Holder.

"As long as he is cooperating and waiving those rights, prosecutors would not be rushing into court and changing that dynamic right now. They want to get as much information out of him as they can," said former U.S. Attorney Randy Mastro.

Meanwhile, there are still questions surrounding Shahzad's self-admitted plot, including who may have funded the college educated yet unemployed and financially strapped father of two.

CNN reports that a high-level U.S.-Pakistani investigation team grilled Shahzad's father in Northwest Pakistan about his son's involvement in the failed bomb attempt.

Authorities now believe Shahzad had ties to TTP, a Pakistani Taliban group. That group claimed responsibility for the attempted attack a day before it happened, later telling CNN it had no ties to Shahzad.

While there's still no word of a court appearance, some say it could happen within the next few days.

"It's hard to believe he will go without appearing before the court for longer than a few more days," said former U.S. Attorney Zachary Carter. "But it could take that long before the authorities have exhausted all the information that satisfies them that there is not a current emergency. That could imminently occur that could be preventing by continuing to mine the information that he provides."

While the Pakistani Taliban praised Shahzad for what the group called "a brave job," the leads federal and state authorities are pressing him for could lead to more arrests.

Shahzad is being charged with detonating a weapon of mass destruction, attempted car bombing and obstructing interstate and foreign commerce by trying to kill and maim United States citizens.
