A 17-year-old girl was arrested Wednesday night in the stabbing of another teen girl outside a high school in Silver Spring, Montgomery County police said.

Briana Sarai Funes, of the 2200 block of Shorefield Road, turned herself in to police one day after the non-fatal stabbing of a 17-year-old Montgomery Blair High School student outside Northwood High School.

According to police, the attack took place Tuesday about 9 p.m., after a boys’ basketball game between Northwood and Kennedy high schools.

Initial police reports, based on witness accounts, indicated that the victim was trying to stop a fight between one of her friends and a female student from Kennedy.

But Funes told police that she intervened when she saw the victim engaged in a physical fight with one of Funes’s friends.

Funes admitted to taking a knife from her jacket pocket and stabbing the victim repeatedly in the back before fleeing in her car, police said.

The victim was taken to a hospital with injuries that were not life-threatening.

Funes has been charged as an adult with attempted homicide, first- and second-degree assault, reckless endangerment, and carrying a dangerous weapon on school property.

Police said that bond and court date information as well as a mug shot were not yet available.
