A 10-year-old girl was tasered by police in London following reports she was threatening a woman with weapons.
The Metropolitan Police has revealed details of the incident in January after a complaint was passed to the police watchdog.
The force told Sky News it was called to a property in southwest London after receiving reports that a girl was “threatening a woman with garden shears and a hammer”.
A Met Police spokesman said: “Officers attended the scene and entered the property. A police Taser was discharged.
“The girl was uninjured but taken to hospital as a precaution.”
The Met Police said it carried out a review of the incident and “no misconduct was identified”.
A formal complaint was received on 27 February and a voluntary referral has been made to the Independent Office for Police Conduct (IOPC), a spokesman added.
The IOPC told Sky News it is assessing the complaint about the incident.
A spokeswoman for the watchdog said: “We have received the referral of a complaint and we are assessing it to determine what further action may be required.”
The incident was first reported by The Sun newspaper.
The Children’s Rights Alliance for England (CRAE) said in 2018 it had seen a “deeply troubling” rise in incidents involving youngsters and urged police to stop firing Tasers at children.
It came after Sky News revealed police had fired Tasers at children as young as 13, elderly people and dozens of animals in the previous three years.
A 77-year-old pensioner and at least 37 dogs were shot with a stun gun by police between January 2016 and November 2018, according to data released by UK forces.
CRAE director Louise King said at the time: “Tasers can inflict intolerable pain and children have told us that the threat of violence from police carrying Tasers is really frightening.
“The government and the police need to take urgent action to protect children’s safety and well-being.”
