NEW YORK - A bloody shootout on a New Jersey street ended Monday with the arrest of a suspect in the bomb blast that wounded 29 people Saturday in New York City’s Chelsea neighborhood, authorities said.

Ahmad Khan Rahami, 28, a US citizen of Afghan origin, and two police officers were wounded in the gunfight in the city of Linden - hours after authorities found more explosives at a New Jersey train station, raided an apartment nearby, issued a wanted poster and began to link the blast with other bombs.

The intense manhunt came to a swift conclusion after Rahamin was found sleeping in the doorway of a bar, Mayor Derek Armstead said. Rahami shot the responding officer – who was wearing a protective vest - in the abdomen, Armstead said.

Rahami then began shooting “indiscriminately” along the city’s Elizabeth Avenue, the police said, and another officer was injured in the hand. More officers joined the gun battle and brought Rahami down, police Capt. James Sarnicki said.

“We have reason to believe this was an act of terror,” New York Mayor Bill de Blasio said, adding “There is no other individual we are looking for right now.”

The FBI wanted poster, issued hours before the arrest, warned that Rahami “should be considered armed and dangerous.”

Rahami’s last known address was listed in Elizabeth, New Jersey, and federal authorities conducted a raid there Monday at an apartment above a fried chicken restaurant operated by Rahami’s father.

Elizabeth Mayor Christian Bollwage said a traffic stop conducted by FBI agents in New York City led to the search warrant in Elizabeth.

The search of Rahami’s home did not immediately reveal evidence that explosives had been assembled there, a federal law enforcement official said.

AFP adds: President Barack Obama, in New York on Monday attending the UN General Assembly with world leaders, called on Americans “not to succumb to fear” in his first remarks about the three attacks in the same 24-hour period.

“Even as we have to be vigilant and aggressive both in preventing senseless acts of violence but also making sure that we find those who carry out such acts and bring them to justice, we all have a role to play as citizens in making sure that we don’t succumb to that fear,” he said.

Obama stressed that investigators at this point saw “no connection” between the incidents on the East Coast and the Minnesota stabbing, where police said the attacker made “some references to Allah” in carrying out the attack.

Ahmad Khan Rahami, 28, was shown stretchered into an ambulance, sporting a bloodied bandage on his right arm and moving his head with his eyes open in the New Jersey town of Linden, according to ABC News footage.

Two police officers were also shot and hurt in the exchange, said the mayor of the suspect’s neighboring hometown Elizabeth, adjacent to Newark International Airport.

“Mr Rahami is currently under arrest,” Mayor Chris Bollwage told CNN. “One police officer in the city of Linden was shot in the chest and one was shot in the hand. Mr Rahami also sustained shots,” Bollwage added.

His arrest came around four hours after the FBI released a mugshot of the brown-haired and bearded Rahami, calling him “armed and dangerous,” in text message alerts sent to millions of people in the New York area.

FBI officers late Sunday also found and defused a nest of bombs planted at the train station in Elizabeth.

Police want to question Rahami in connection with Saturday night’s bombing in New York’s Chelsea neighborhood that injured 29 people and Saturday morning’s Seaside Park pipe bombing, which forced the cancellation of a US Marine race.

The discovery of the nest of bombs in Elizabeth may also be linked to the two attacks in New Jersey and in Manhattan, where a pressure cooker bomb was also successfully defused.

“From the bombs that were undetonated you can often get good evidence. You can get finger prints, DNA etc,” New York Governor Andrew Cuomo said on CBS.
