The victim has been identified as a 17-year-old student at Montgomery Blair High School. The suspects are believed to be students at Kennedy High School.
According to police, the altercation broke out outside of Northwood High School on University Boulevard West about 9 p.m.
The girls were at the school to watch a boys’ basketball game between Northwood and Kennedy high schools, police said.
After the game, the victim went outside and saw one of her friends involved in a dispute with another girl. The victim was attempting to stop the fight when she was stabbed several times in the lower torso, police said.
She was taken to a local hospital with non-life-threatening injuries, police said.
According to witness accounts given to responding officers, two girls were involved in the stabbing. They are both believed to be current students at Kennedy High School.
Police did not say what the initial dispute was about, but, according to Eric Minus, Kennedy High School’s principal, the fight was not connected to the basketball game.
Police say the stabbing is still under investigation. Anyone with information about the incident or the suspect can call 301-565-5835.
