A high-ranking law enforcement official told CBS News that the suspect, identified by multiple sources as 23-year-old Nigerian Umar Farouk Abdulmutallab apparently used a syringe to inject a chemical into powder located near his groin, a technique not seen in previous attempted attacks.
Schuringa told CNN he heard a sound similar to a firecracker as the Detroit-bound flight was preparing to land. After seeing smoke, he noticed a burning object between Abdulmutallab's legs.
"I pulled the object from him and tried to extinguish the fire with my hands and threw it away," Schuringa told CNN. (Watch video below).
Schuringa said his hands were "pretty burned" after incident, but said the injuries were minor.
"I am fine. I am shaken up. I am happy to be here."
Schuringa said he stripped off the suspect's clothes to make sure he didn't have any more explosives on him and helped a crew member handcuff him.
He described Abdulmutallab as "was staring into nothing" following the thwarted attempt.
