They say the victims, a 19-year-old CU student and her 20-year-old male friend, were walking when the woman flipped off two men who were yelling vulgar comments at them.
One of the suspects got the woman in a chokehold and pushed her to the ground. The other suspect tackled her friend and held him down while punching him.
The attackers are described as white males in their 20s. They are between 5 feet 5 inches and 5 feet 10 inches tall. One of the men had dirty blond hair in a ponytail and glasses. The other suspect had curly brown hair.
