CHELSEA, Manhattan (WABC) -- The FBI is questioning five people who were taken into custody in connection with Saturday's bombing in Chelsea.
At 8:45 p.m. Sunday the FBI and NYPD conducted a traffic stop of a vehicle of interest in the investigation into the bombing.
The men were in a car stopped on the Belt Parkway. They were headed from Staten Island to Brooklyn on the Verrazano-Narrows Bridge.
Five people inside, possibly family members and from New Jersey, were taken to an FBI building for questioning. There were concerns they may have been on their way to the airport.
No one has been charged yet with the explosion, and the investigation is currently ongoing.
"This was an intentional act, but we do not know the motivation. That's what we have to do more work on," said Mayor Bill de Blasio. "We know there was a bombing. We will be very careful and patient to get to the full truth here."
On Sunday, a federal law enforcement official said the Chelsea bomb contained a residue of Tannerite, an explosive often used for target practice that can be picked up in many sporting goods stores. The discovery of Tannerite may be important as authorities probe whether the two New York City devices and the pipe bomb in Seaside Park, New Jersey are connected.
Cellphones were discovered at the site of both bombings, but no Tannerite residue was identified in the New Jersey bomb remnants, in which a black powder was detected, said the official, who wasn't authorized to comment on an ongoing investigation and spoke to the AP on condition of anonymity.
Late Sunday, five suspicious devices were found near a train station in Elizabeth, New Jersey. Elizabeth Mayor Christian Bollwage said the devices were found in a bag in a trash can by two men who reported seeing wires and a pipe coming out of the package. One of the devices exploded as a bomb squad used a robot to try to disarm it. No injuries were reported.
While the investigation of the Chelsea blast continues, only one block of West 23rd Street remains closed, between 6th Avenue and 7th Avenue.
Subway service has resumed, including on the number 1 line, while train station stops at 23rd Street and 28th Street have been restored in both directions.
During this time, the exit staircase at the northeast corner of 23th Street and 7th Avenue remains closed. Passengers can use the staircase located on the southeast corner of 23th Street and 7th Avenue.
New York City will open a Resident Service Center which will be located inside of the NYC Emergency Management vehicle located on the northeast corner of West 23rd Street and 7th Avenue in Manhattan. Assistance will be available from 8 a.m. to 9 p.m. Monday and Tuesday.
