The boy had been threatening to attack his mother and the officers, police said, and though they tried to convince the boy to drop his weapons and employed other deescalation tactics, the officers eventually feared for their lives, said Carroll County Sheriff spokesman Jim DeWees to the Carroll County Times. At this point, the officers used a Taser.
"It appears the deputies acted appropriately and used the right amount of force under the circumstances," DeWees said.
The officers did not arrest the boy and only used the stun gun to disarm the boy, the Times reported. He will not be charged with any crimes.
"Anytime a situation arises where a taser is used on a 9-year-old child, especially an autistic child, we are obviously concerned about ensuring the matter is thoroughly reviewed," said State Attorney Brian DeLeonardo in a statement. "Nevertheless, we have not been asked to review this incident at this time. I can assure you, contrary to some media reports, we are not considering charges against the autistic child."
The boy was taken to Carroll Hospital with injuries from the encounter, the Times reported.
"At the end of the day, after looking at it, I'm extremely proud of how they handled the situation. Very difficult," DeWees said.
The case is being reviewed internally, reported CBS Baltimore.
