The wife of the man behind the deadly terrorist attack at Pulse nightclub in Orlando has been arrested on charges stemming from the mass shooting that killed 49 people, federal authorities said Monday.

Noor Salman was taken into custody by FBI agents Monday at her home outside of San Francisco. Prosecutors had been weighing charges against her in the aftermath of the June 12, 2016, attack that killed 49 people and injured more than 50 others. 

Salman's husband, Omar Mateen, was killed in a shootout with police during the rampage in the gay club located just south of downtown Orlando.

Orlando Police Chief John Mina in a statement said Salman was taken into custody on charges of aiding and abetting by providing material support to a terrorist organization and obstruction of justice.

"I am glad to see that Omar Mateen's wife has been charged with aiding her husband in the commission of the brutal attack on the Pulse nightclub," Mina said. "Federal authorities have been working tirelessly on this case for more than seven months, and we are grateful that they have seen to it that some measure of justice will be served in this act of terror that has affected our community so deeply."

Continued Mina: "Nothing can erase the pain we all feel about the senseless and brutal murders of 49 of our neighbors, friends, family members and loved ones. But today, there is some relief in knowing that someone will be held accountable for that horrific crime."

FBI agents questioned Salman in the aftermath of the shooting about whether she had advance knowledge of her husband's attack. Salman told The New York Times in an interview published last fall that she knew her husband had watched jihadist videos but that she was "unaware of everything" regarding his plans to shoot up the nightclub. She also said he physically abused her.

"Noor Salman had no foreknowledge nor could she predict what Omar Mateen intended to do that tragic night," her attorney, Linda Moreno, said in a statement reported by The Associated Press. "Noor has told her story of abuse at his hands. We believe it is misguided and wrong to prosecute her and that it dishonors the memories of the victims to punish an innocent person."

Salman is expected to make her initial appearance at 9:30 a.m. Tuesday at the federal courthouse in Oakland, California.
