text: Quick-thinking: Brady Olson, a teacher at North Thurston High, took down a gunman on Monday . A Washington high school teacher is being hailed a hero for tackling a 16-year-old student to the ground after he opened fire on Monday morning. No one was injured after the boy shot twice toward the ceiling in the school commons before classes began at North Thurston High School in Lacey, about 60 miles southwest of Seattle, authorities said. Brady Olson, who teaches Advanced Placement government and civics at the school, knocked the armed student to the ground and kept him pinned down until authorities arrived, witnesses said. The shooter is in custody at the Lacey Police Station. The teenager, who has not been identified, only transferred to the high school a month ago, according to authorities. He later told police he shot into the air because he didn't want to hurt anyone. A search warrant is being carried out at his home, police said. School district spokesperson Courtney Schrieve confirmed that the 43-year-old teacher had been responsible for helping apprehend the student. 'He is a very brave man who probably saved a lot of people today,' Schrieve told KCPQ. Both students and staff said they were not surprised that Olson, who has taught at the school for nine years, was the one to stop the shooter. 'If anyone in the school were to do something like he did, I would think it would be him,' said student Teia Patan, 17, who is in one of Olson's classes. 'He's one of those people who watch over kids.' Scene: A 16-year-old student walked into the commons, pictured, on Monday with a gun and cigarette and fired two shots at the ceiling, according to witnesses. Mr Olson then tackled the boy to the ground . Fears: Parents and students walk away from North Thurston High School on Monday after a 16-year-old student opened fire before classes at the school and was stopped by a teacher . Patan was swept into a classroom and then escorted out of the building after the shooting. He described his high school as a nice, calm school, with no bullying. 'When it was happening, I first thought it has to be fake,' he added. Another student, 16-year-old Anthony Rybalkin, told the News Tribune that he was in the commons area when the shots were fired. 'I saw (the student) walking down the stairs with a cigarette and gun in his hand,' Rybalkin said. 'I was like, "This is actually happening".' He watched as Olson tackled the boy to the ground. He said that another teacher then helped him hold the teenager down. Olson, who is married to an elementary teacher in the school district, Shara Olson, has been teaching for nearly 20 years and has also worked as a former assistant football coach.

'Thank you so much Mr.Olson for saving so many lives and having the courage to do that,' one wrote. Another added: 'Mr Olson part-time teacher, full-time super hero.' And on her Facebook page, Olson's own mother added: 'So proud of Brady. Not a surprise to any of us that he would be so brave. It was an automatic reaction for him.'
