NEW YORK -- FBI agents pulled over a car on a highway in Brooklyn on Sunday night and were questioning its occupants in connection with the investigation into the, authorities said.
Agents stopped “a vehicle of interest in the investigation” at 8:45 p.m. Sunday, according to FBI spokeswoman Kelly Langmesser
She wouldn’t provide further details, but a source told CBS News five people were being interrogated.
No one has been charged with any crime and the investigation is continuing, Langmesser said.
State Sen. Martin Golden said on Instagram that the incident may be connected to the Chelsea bombing, but that hadn’t been confirmed, reports CBS New York.
The bomb that rocked a bustling Manhattan neighborhood contained residue of an explosive often used for target practice that can be picked up in many sporting goods stores, a federal law enforcement official said Sunday, as authorities tried to unravel who planted the device and why.
The discovery of Tannerite in materials recovered from the Saturday night explosion may be important as authorities probe whether the blast was connected to an unexploded pressure-cooker device found by state troopers just blocks away, as well as a pipe bomb blast in a New Jersey shore town earlier in the day.
Gov. Andrew Cuomo, touring the site of the blast in Manhattan’s Chelsea neighborhood, known for its vibrant arts scene and large gay community, said there didn’t appear to be any link to international terrorism. He said the second device appeared “similar in design” to the first, but didn’t provide details.
“We’re going to be very careful and patient to get to the full truth here,” Mayor Bill de Blasio said Sunday. “We have more work to do to be able to say what kind of motivation was behind this. Was it a political motivation? A personal motivation? What was it? We do not know that yet.”
Tannerite was discovered at the site of both Manhattan devices, sources tell CBS News.
However, no Tannerite residue was identified in the New Jersey bomb remnants, in which a black powder was detected, said an official who spoke to The Associated Press on condition of anonymity because the official was not authorized to comment on an ongoing investigation.
Authorities said the Manhattan bombing and the, didn’t appear to be connected, though they weren’t ruling anything out. The New Jersey race was cancelled and no one was injured.
A source tells CBS News three cell phones with the two New York devices and one associated with the Seaside Park device are described as flip phones.
Officials haven’t revealed any details about the makeup of the pressure-cooker device, except to say it had wires and a cellphone attached to it.
Technicians in Quantico, Virginia, were examining evidence from the Manhattan bombing, described by witnesses as a deafening blast that shattered storefront windows and injured bystanders with shrapnel in the mostly residential neighborhood on the city’s west side. All 29 of the injured people were released from the hospital by Sunday afternoon.
On Sunday night, investigators examined a, that forced the suspension of service on the busy Northeast Corridor line. Amtrak said later Northeast Corridor service would operate on a modified schedule Monday.
