Deputies showed a lot of restraint and did not shoot the teen, CBS Atlanta reported. Instead, they distracted him with an explosive device.
'It got his attention,' said Sheriff Miller. 'We sent a K-9 unit in and he hit the K-9 dog with the butt of the pellet gun. At that point, we tased him then took him into custody.'
Stand-off: Douglas County Sheriff Phil Miller said the boy waved the sword around and shot at police with a pellet gunHistory of violence: The 14-year-old had been arrested twice before this year, once having a different sword confiscatedFamily members told CBS Atlanta the teen lost it when he was told he would have to stop playing a video game soon.
Sheriff Miller said the incident on Monday was the third time this year deputies were called about the teen being violent.He said: 'We've arrested him on two different occasions. Once in June where he had another sword, which is in evidence. This is not the same sword. He cut his grandmother on the foot with it that time.'
Police arrested him again on July 29.
Neighbour: Pam Mayercik, who lives across the street, said the boy would wave at her but seemed a little different'We almost had to hog tie him to not hurt him,' said Sheriff Miller, adding that each time deputies arrested the teen, they took him to the hospital for evaluations and doctors released him.
'Obviously he was a danger to himself, a danger to his family and a danger to this community,' said Sheriff Miller.Pam Mayercik lives across the street from the family. She told CBS Atlanta she often saw the teen in the neighbourhood.
'I used to wave to the kid all the time,' she said. 'He seemed like he was a little bit different. He's just a little kid with glasses and kind of shy.'
