NEW YORK -- The FBI has taken 28-year-old Ahmad Khan Rahami in custody.
He was shot while being taken into custody.
Two officers were hit in the shootout.
One officer's vest was struck, and the other was shot in the hand.
They want to speak with him about the explosion Saturday in Seaside Park, New Jersey as well as the explosion in New York.
Surveillance videos showed the same man near the site of the explosion and another location where a pressure-cooker device was found four blocks away, multiple local and federal law enforcement sources told CNN.
Saturday's explosion shook New York City's Chelsea neighborhood and sent panicked people scrambling for cover.
By Sunday, 26 of the 29 injured who had been admitted to hospitals had been released.
A few blocks away from the blast site and shortly after the explosion occurred, investigators found one possible lead: a pressure cooker, with dark-colored wiring sticking out, connected by silver duct tape to what appears to be a cellphone, officials said.
Shortly before 9 p.m. Sunday, the FBI and NYPD conducted a traffic stop of a vehicle of interest in the investigation, according to a statement from FBI.
No one has been charged with any crime and the investigation is ongoing, the statement said.
