Investigators late Sunday arrested five people in connection with the bombing in New York City, according to ABC News.
Tonight we are learning more about the potential ingredients in an explosive that detonated in Manhattan’s Chelsea neighborhood.
The blast injured 29 Saturday – and nearby surveillance captured the force of the blast on windows and scattered debris.
A law enforcement source told The Associated Press in a report there is residue of a product called “Tannerite” found at the blast site.
You can find it in any North Texas sporting goods store next to ammunition. It’s commonly used in target practice.
Travis Bond owns DFW Shooters Academy in Highland Village and knows plenty about Tannerite.
“You shoot it with a rifle and it’s a loud bang and a puff of smoke,” Bond said.
Tannerite is a mix of two powders, ammonium nitrate and aluminum powder. When mixed together they produce an explosive powder that remains stable until it meets a powerful catalyst.
“Then it has to be ignited by a high velocity round,” Bond said.
It is still too early to know what triggered the detonation Saturday.
Investigators on Sunday were looking at possible links to an unexploded pressure cooker bomb found four blocks away and a pipe bomb that detonated in New Jersey earlier Saturday.
