The FBI has arrested the wife of Omar Mateen, the man who planned and carried out the deadly terrorist attack at a gay nightclub in Orlando, Florida that left 49 people dead and 53 others wounded.
Mateen's wife, Noor Salman, was taken into custody by the FBI on Monday and is suspected of obstruction relating to the case, the New York Times reported.
Authorities began investigating Salman hours after Mateen was killed in a shootout with police during his shooting rampage in June 2016. They reported at the time that Salman had given conflicting information about her knowledge of Mateen's attack, which was the deadliest mass shooting in United States history.
During his interaction with police before he was killed, 29-year-old Mateen proclaimed his allegiance to the Islamic State terrorist group also known as ISIS.
Salman is expected to appear in court on Tuesday in San Francisco.
