A 17-year-old student is in custody and all school lockdowns have been lifted.
The student arrested will face an attempted murder charge, and possibly additional charges, according to Santa Rosa Police Captain John Cregan.
The two students had a verbal altercation that led to the 17-year-old student shooting several rounds from a handgun, hitting the 16-year-old twice, Cregan said.
TAKE ACTION: Get help with improving our schools
Police say that after conducting a thorough sweep of the campuses placed on lockdown, they found no evidence that the weapon used is on campus.
There are no further reports of violence in the area and police say there is no threat to students.
Police say the handgun used in the shooting is still on the street. A student was handed a backpack with the gun inside and left campus in a car, Cregan said, but it's possible the student didn't know what was in the backpack.
"This we know is a very unnerving and traumatic incident for our students, for our teachers, for the community," Cregan said.
He asks that any students with information or video of the incident call SRPD's Violent Crimes Team at 707-543-3590.

Students at Ridgway High, Santa Rosa High and the Santa Rosa Junior College will remain on campus and continue with their regular schedule.
Sofia Ferguson, a senior, said the lockdown announcement came and they rushed into their PE classroom. Little did she know that two hours later, the student sitting next to her would be arrested.
She said at least a dozen officers with rifles drawn stormed their classroom at 11 a.m. and had them hold their hands up as they searched everyone. She called the experience terrifying.
Police say the 16-year-old was shot just outside the school at 9:12 a.m. Aerial footage shows two suspects in handcuffs being taken into custody and later a third.
Parents were getting text messages and photos from the students on lockdown and many were shaking or crying as they stood outside the school worried. By 11:30, the lockdown was lifted and students were released.
