MILLBRAE -- The 16-year-old girl wounded late Saturday near Capuchino High School was shot during an apparent drive-by shooting, police said Monday.

A group of about six teens who were hanging out in front of a house in the 600 block of Santa Teresa Way around 10:25 p.m. when a car pulled up and someone in the vehicle opened fire. The car then sped away. Police haven't made any arrests, said San Mateo County Sheriff's Deputy Rebecca Rosenblatt.

The wounded South San Francisco girl was rushed to a hospital, and is expected to recover, she added. No one else was shot.

It remains unclear what provoked the violence. None of the teens lived at the house, Rosenblatt said. It wasn't clear if the shooting was related to street gangs.

Witnesses said they saw a dark-colored sedan speed away south on Santa Teresa and west on Park Boulevard.
