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.
