"The individual has been taken into custody and the FBI New York Joint Terrorism Task Force is investigating the incident."The Joint Terrorism Task Force, first established in New York City in 1980, "is a multi-law enforcement agency that includes NYPD detectives and FBI special agents who investigate terrorism in the New York City metropolitan area and around the world," according to the New York City Police Department.Footage from the scene shared on social media showed a plume of smoke rising while officers tackled someone to the ground and blocked off the area.
