An inquiry is under way after a Taser gun was used by police on a 16-year-old schoolboy.
The weapon was deployed as officers responded to an emergency call from the teenager's mother.
She dialled 999 when her son had locked her out of the family home in Wythenshawe, Greater Manchester, following an argument. The woman reportedly told the officers the age and name of her son who later came out of the property.
He then said he came out with his hands out but was then "jumped on" which led to a scuffle before the stun gun was used.
The boy was arrested on suspicion of assaulting two police officers but was later told he would face no charges. His family - who do not wish to be named - want an apology and are considering taking legal action.
A spokesman for Greater Manchester Police said: "Police were called to Aldfield Road, Northern Moor, following reports of a domestic dispute. Officers attended and, while arresting a 16-year-old boy, a Taser was deployed.
"He was arrested on suspicion of assaulting two police officers. The Crown Prosecution Service later decided that no further action would be taken against the boy.
"A GMP Professional Standards Branch (PSB) investigation is ongoing into the circumstances surrounding the use of a Taser during the arrest. In line with protocol, it was referred to the Independent Police Complaints Commission and the PSB investigation is being supervised by them."
Speaking about the incident on the afternoon of June 30, the boy told the Manchester Evening News: "I came out, held my hands up and said 'I want to negotiate with my mum'. The next moment they all jumped on me. There was a scuffle and they tried to throw me to the ground but I wouldn't go down so they Tasered me. I didn't know what was happening."
His mother said to the newspaper: "I thought they would just get him out of the house and take him to his sister's or something to calm down. I was shocked at the response."
