HONOLULU (AP) -- A police officer shot a 17-year-old runaway in the wrist Tuesday morning at a Hawaii high school after the teen cut one officer with a knife and punched two others, authorities said.State Department of Education spokeswoman Donalyn Dela Cruz said the boy showed up at Roosevelt High School near downtown Honolulu, and officials there recognized him as a runaway and called police. The boy had been a student at the public school before but wasn't registered for classes there this semester, she said.Honolulu Police Maj. Richard Robinson said officers arrived at the school and tried to take the boy into custody, but he lunged at them.The teen attacked one of the officers with a knife, leaving him with a minor cut on his torso, Robinson said. He also hit two other officers, but neither suffered serious injuries.One of the officers then fired two shots, hitting the boy once in the wrist. The teen was taken to a hospital in serious condition, EMS spokeswoman Shayne Enright said. His injuries were not life-threatening.The incident prompted a lockdown at Roosevelt, which has an enrollment of about 1,500.Noah Powell, a 16-year-old junior, said the shooting happened in a school counselor's office. Powell said he was in a nearby office and heard the struggle and shots, but he didn't see the 17-year-old or know who he was.Powell texted his parents afterward to let them know he was OK. He said he also posted on Facebook that he was fine and got quick responses from people saying they were praying for the school.Kealii Akiona-Soares, a junior, was in social studies class when he heard a faint shot at about 8:20 a.m.Then a school bell sounded and students were kept in their classrooms, the 17-year-old said. He said his class continued with a politics lesson, and everyone kept mostly calm.\I guess it happens a lot in mainland schools
