Officers responded around 9:40 p.m. to reports of a shooting in the 3100 block of Oakgate Way and found a man suffering from at least one gunshot wound, San Jose police spokesman Officer Albert Morales said.
The man was taken to an area hospital where he remained as of Saturday afternoon.
Morales said he did not have information about the man's condition.
The shooting was apparently sparked by a fight between the victim and his friends and the shooter and his friends in the area of Quimby Oak Middle School at 3190 Quimby Road, the spokesman said.
Officers searched the campus and the surrounding area but were unable to locate the suspects, who had fled the scene.
Morales said it does not appear that the gunman and victim knew one another before the confrontation, nor does it appear to be a gang-related attack.
Police continue to investigate the shooting and are attempting to locate the shooter.
