Ahmad Khan Rahami is considered separate from the five people detained on Sunday, a source tells PEOPLE
Authorities have named Ahmad Khan Rahami as a person of interest in the bombing in the Chelsea neighborhood of New York City on Saturday. Authorities are seeking him out to talk about the explosion.
The FBI say that Rahami, 28, was born in Afghanistan and is believed to be living in Elizabeth, New Jersey.
In a press release from the FBI, Rahami, who is a U.S. citizen, should “be considered armed and dangerous.” Anyone with information about Rahami should call the FBI’s toll-free tipline at 1-800-CALL-FBI. Authorities also pushed a cellphone emergency alert to New York-area residents urging them to call 911 if they see Rahami.
A federal source confirms to PEOPLE that Rahami is considered separate from the five people who were detained by the FBI on Sunday night. Those individuals were taken in for questioning during a traffic stop at the Verrazano-Narrows Bridge, the bridge that connects the boroughs of Brooklyn and Staten Island. The FBI states that no one has been charged with any crime as the investigation is ongoing.
The federal official also confirms to PEOPLE that the same model flip-style cell phone was used as a detonator for the two bombs in Chelsea (a second device was discovered on Saturday night and disarmed by authorities) and the bomb that went off ahead of a charity run in Seaside Park, New Jersey, which is about 85 miles south of Manhattan. Both bombings occurred within hours of each other on Saturday.
No one was injured in the Seaside Park bombing. Twenty-nine people were injured in the Chelsea bombing but none of the injuries are considered to be life-threatening.
Early Monday morning a police robot detonated a backpack full of pipe bombs in Elizabeth, which is about 20 miles from Manhattan. A federal source tells PEOPLE that it unclear if the same style of flip-phone was connected to the bombs found in Elizabeth.
The source adds that investigators believe the five persons of interest detained are from Elizabeth, New Jersey, but have not yet confirmed any connection to the devices found there overnight.
Authorities in New York had previously announced that they were beefing up security around the city after the explosion in Chelsea. The city had already been on high-alert as foreign diplomats have already begun defending on the city to prepare for the General Assembly at the United Nations, which will begin on Tuesday.
