A suspected gang member opened fire on a group outside a Portland high school, sending three young people to the hospital in what police said appeared to be a gang-related shooting.
The victims are students at Rosemary Anderson High School or in affiliated job training programmes, Sergeant Pete Simpson said. A 16-year-old girl was in critical condition, and two males, aged 17 and 20, were in fair condition, police said. A 17-year-old girl was grazed by a bullet but not hospitalised.
Witnesses told police there may have been a dispute outside the school before the shooting occurred at a street corner.
The assailant and two people fled, and the wounded students went to the school for help, the spokesman said.
"Based on the investigation thus far, the shooting appears to be gang-related," Simpson said.
