The confrontation between the armed student and Lowe, who is a football coach, track and field coach and security guard at the Northeast Portland school, occurred inside the school after the student entered a classroom. Police initially said the encounter happened near the school's tennis courts. Police recovered a gun at the scene. Police have not said whether shots were fired.

In a series of tweets Saturday afternoon, Lowe said he’s happy no one was hurt and is determined to be part of the solution to stop gun violence at schools.

“When I signed up to be a Security Guard, Football and Track & Field Coach for Parkrose High School, I did so to guide and coach young people whose shoes I had once been in. I had no idea, that I would one day have to put my life on the line like I did yesterday for my students.

“When confronted with the test the universe presented me with, I didn't see any other choice but to act. Thank God, I passed. I've spent the last 24 hours being more appreciative of my family and realizing we have a serious problem.

“I'm blessed to be alive and extremely happy that the students are safe. I'm not sure what's next, I haven't had the time to really think about it. But I am sure I want to be a part of the solution to school gun violence. Thank you @PortlandPolice for your help #ParkroseHighSchool.”

Student Sisi Fuapau said he saw Lowe take the armed student to the ground.

“It was crazy seeing him. He was a wide receiver for the Ducks. I didn’t know he could tackle like that. It was crazy,” Fuapau said.

Police on Saturday identified the student as 18-year-old Angel Granados Dias. A parent told The Oregonian students said Dias intended to use the gun to harm himself.
