Law enforcement arrested the wife of the man who killed 49 people at a gay Orlando nightclub last June, officials announced Monday.

FBI agents took into custody Noor Salman, wife of Omar Mateen, at her home outside of San Francisco. A source told the New York Times that Salman is being charged with obstruction.

Investigators say Salman was not truthful with them when they interviewed her hours after the attack. Mateen was killed in a shootout with police, ending the attack.

Noor, according to the ABC News, is expected to appear in court on Tuesday.
