From Wikipedia:

A scuffle broke out when a woman in handcuffs was escorted (read "dragged") from the door of the bar to the waiting police wagon several times. She escaped repeatedly and fought with four of the police, swearing and shouting, for about ten minutes. Described as "a typical New York butch" and "a dyke–stone butch", she had been hit on the head by an officer with a baton for, as one witness claimed, complaining that her handcuffs were too tight.[66] Bystanders recalled that the woman, whose identity remains unknown (Stormé DeLarverie has been identified by some, including herself, as the woman, but accounts vary[67][note 4]), sparked the crowd to fight when she looked at bystanders and shouted, "Why don't you guys do something?" After an officer picked her up and heaved her into the back of the wagon,[70] the crowd became a mob and became violent.

Emphasis and parentheses mine. Stormé was biracial and androgynous
