Ahmad Khan Rahami, a person of interest in the bombings, was injured in a shootout with police on Monday and taken into custody
A person is in custody following multiple explosions this weekend in New Jersey and New York City, a manhunt and a shoot-out with authorities.
Despite more than two dozen injuries, no one has been killed in the violence.
Here are seven facts – and three unknowns – about the case:
1. There were three separate explosions.
A federal counterterrorism official, detailing the timeline of incidents, tells PEOPLE that on Saturday morning, a bomb went off just before a charity run in Seaside Park, New Jersey, which is about 85 miles from Manhattan. One pipe bomb exploded in a trash can along the 5K’s route while two other pipe bombs were rendered safe, according to the official.
“One of the devices had Christmas tree lights wrapped around it,” the federal official tells PEOPLE. “An intact flip phone with protruding wires was also found in the area.”
It appeared that no one was injured in that explosion, according to The New York Times.
On Saturday night, a homemade bomb exploded in a portable construction dumpster on 23rd Street between Sixth and Seventh Avenues in Manhattan’s Chelsea neighborhood – a popular hot spot that is usually busy on weekend nights – injuring 29 people, according to the official.
A fusing system with AA batteries as well as parts of a pressure cooker, flip phone and nylon fabric and a zipper were found at the scene, the official says.
Everyone injured in the explosion has been released from the hospital, NBC News reports.
Late Saturday, about two hours later, an unexploded pressure cooker with a flip phone attached was discovered on west 27th Street in New York City, the federal official tells PEOPLE. It was rendered safe and removed.
Despite reports early Sunday of a third device at 48th Street and Fifth Avenue, no device was located, the official says – but Sunday night, a bag containing five pipe bombs was found at a train station in Elizabeth, New Jersey.
One device was detonated by a bomb disposal robot, the official says. No one was injured.
2. The same man, Ahmad Khan Rahami, is a suspect in all three explosions in New Jersey and N.Y.C., the official says.
The FBI’s William Sweeney said at a Monday news conference that evidence “directly links Rahami to the devices in both New York and New Jersey.”
The federal counterterrorism official later confirmed to PEOPLE that Rahami is a suspect in the Elizabeth explosion as well as the Chelsea and Seaside Park bombings.

3. Rahami was apprehended after a shoot-out with police in New Jersey.
Less than two days after the explosion in Chelsea, officials honed in on Rahami. The 28-year-old is a U.S. citizen living in New Jersey who immigrated from Afghanistan, according to authorities.
Johnathan Wagner, 26, tells PEOPLE he grew up with Rahami and that his relatives were “nice” people who would sometimes give Wagner food.
“I never thought someone in the family would do something like this,” Wagner tells PEOPLE.
After the bombings, a hunt for Rahami ensued and police responded after a Linden, New Jersey, resident spotted the 28-year-old in front of a bar, the Times reports. A shootout took place about 10:30 a.m. Monday after Rahami allegedly opened fire on the officers.
Two officers were wounded, Elizabeth Mayor Christian Bollwage said at a Monday news conference.
Both officers are expected to survive, the federal official tells PEOPLE, adding that Rahami was shot three times: in the arm, the abdomen and the leg.
Rahami was undergoing medical treatment as of 1 p.m. Monday, the official says, and is not cooperating with investigators.
4. The FBI detained five people Sunday night in connection with the Chelsea explosion, but those people were not charged, official says.
Authorities have said Rahami is considered separate from the five people who were detained.
The federal official says they were stopped in a vehicle associated with Rahami as they drove to the Kennedy Airport from an Elizabeth address. The five were detained for questioning by the FBI, the official says.
Authorities also raided a home in Elizabeth as part of the investigation, the Times reports.
Two search warrants have been obtained for addresses linked to Rahami, the federal official says, and searches continue as of this morning.
5. New York Gov. Andrew Cuomo has called the Chelsea bombing an act of terrorism.
“A bomb exploding in New York is obviously an act of terrorism,” Cuomo said at a news conference. “A bomb going off is generically a terrorist activity. That’s how we’ll consider it. And that’s how we will prosecute it.”
However, the governor said earlier that although the explosion was “intentional,” there was no connection to terrorism and no one had immediately claimed responsibility, the Times reports.
N.Y.C. Mayor Bill de Blasio avoided calling the act terrorism, saying at a news conference that, “There’s no specific and credible threat against New York City at this time from any terror organization.”
6. President Barack Obama has said the explosions are not connected to a stabbing attack at a Minnesota mall, which the federal official echoed to PEOPLE.
Obama added that the stabbing attack is being investigated as an act of terrorism.
7. An emotionally disturbed person falsely claimed responsibility for the bombings.
The federal counterterrorism official tells PEOPLE that someone in North Carolina used a Tumblr account to falsely claim responsibility for the bombings. The official described this person as emotionally disturbed and said they had no connection to the case.
The individual has been taken into custody, the official says, though it was not immediately clear if they will face charges.
1. What was the alleged motive?
As of Monday, Rahami had not been charged with any crime, and the federal official tells PEOPLE that authorities are working to identify his overseas connections and possible ties to radicalism, if any.
Authorities are also working to determine if Rahami was allegedly inspired by any terrorist groups, the official says.
2. Did the suspect allegedly act alone?
As investigators work to learn more about the explosions, it is unclear just how many people were involved in carrying out the bombings. The federal official says they are still working to determine who placed the bombs in Seaside Park, and that there were some similarities in that incident to the Boston Marathon bombing.
3. Why were the locations selected?
Police have said they believe Rahami is behind the bombings, but it is unclear why the particular sites were selected.
