A woman named Barbara Lee saw the crew of men communicating with each other and mistook their signs for gang signs.

She became enraged and the 45-year-old woman confronted them as they motioned for her to leave them alone.

She left the bar and returned later with a juvenile and 19-year-old Marco Ibanez.

They proceeded to stab Stewart and his friends who were out celebrating a birthday. The bouncer was hit with a bottle while Stewart and his party suffered wounds to their back and torso.

Lee and her cohorts were arrested and charged with assault with a deadly weapon. Check out the news footage.
