The suspect in Saturday's bombings in NY and New Jersey declared that "the sounds of bombs will be heard in the streets" and praised "Brother Osama Bin Laden" in a journal found on him when he was arrested, authorities said.
A law enforcement official said that Rahami's father, Mohammad R. Rahami, had called New Jersey police two years ago over a dispute involving his son, but later retracted his complaint.
Before the federal charges were filed, Rahmani was already being held on 5.2 million dollars' (£4m) bail, charged with the attempted murder of police officers during the shoot-out that led to his capture Monday outside a bar in Linden, New Jersey.
Also Wednesday, a homeless man who took a backpack from a garbage can near a train station in Elizabeth, New Jersey, on Sunday night, not knowing it contained pipe bombs prosecutors say were made by Rahami, said he's grateful he didn't prompt an explosion.
Rahami left 12 fingerprints on one of the bombs he planted and bought materials for his bombs under his own name on eBay over the summer, according to federal charging documents. In a handwritten journal, he warned that bombs would resound in the streets and prayed he'd be martyred rather than caught, authorities say.
In separate complaints filed in U.S. District Court in the Empire and Garden States, Rahami was charged with several counts of using weapons of mass destruction, bombing a place of public use, and attempting to destroy property by means of fire or explosives.
Four blocks away, on West 23rd Street in Manhattan's Chelsea neighborhood, a device exploded Saturday night in a garbage bin wounding as many as 31 people, investigators said. Also, cell phones, ones that investigators believe Rahami turned into timers to set off the improvised explosives. "Death to your oppression".
Ahmad Khan Rahami was arrested in connection with the bombings in NYC and New Jersey earlier this week.
The FBI has said the suitcase could be a "really rich environment" for evidence and a "key part" of the investigation, she said.
The FBI never interviewed Ahmad Rahami, according to officials.
Rahami was born in Afghanistan, came to the U.S.at age 7 and became a naturalized American citizen.
"The FBI conducted internal database reviews, interagency checks and multiple interviews, none of which revealed ties to terrorism", the bureau said.
However, Rahami's wife eventually made it to the United States - and she left before Saturday's attacks, according to a law enforcement official.
- Officials are trying to determine whether Rahami's wife is still in the country. Fox News is told that she voluntarily gave a statement to USA officials in the United Arab Emirates.
