According to the L.A. County D.A.'s Office ... several witnesses to the October incident said Azealia repeatedly used a racial epithet and was verbally aggressive to people in Crowe's room.
The witnesses also backed up what TMZ first reported ... that Azealia picked up a glass and threatened to use it to cut the throat of a guest. Azealia filed a police report after the incident claiming Russell choked her, called her the n-word and spit on her as he removed her from the suite.
The D.A. concluded that Russell physically tossing her was "justified to prevent the imminent violence threatened by Banks." Russell also hired high powered attorney Shawn Holley to defend him against the allegations he said were false. As for the spitting ... the D.A. says it was "incidental to preventing more serious threatened violence."
For the record, a witness says the spit didn't hit Azealia anyway.
