A 14-year-old boy will appear in court on Monday charged with murdering a boy aged 12.
The body of Roberts Buncis was found on Saturday in Fishtoft, near Boston, Lincolnshire police said.
The force said in a statement: “Following formal identification we are now in a position to name the boy who lost his life in this tragic incident as 12-year-old Roberts Buncis.
“A 14-year-old boy has been charged with his murder. He has been remanded and will appear at court this morning.”
The 14-year-old suspect cannot be named because he is under the age of 18. A 19-year-old man arrested on Saturday remains in police custody.
Buncis is believed to have been a pupil at Haven High academy in Boston. In a Facebook post, the school said there had been a “very serious incident in the community”.
The school urged children and their parents to contact Lincolnshire police if they could help the investigation.
It added: “Many of you will have already seen details of this on social media. Due to the nature of the murder investigation we are unable to make any further comment. All we can ask at this time is for our community to be respectful and think about the feelings of the family who have lost a loved one, at this time of year.”
Police were called to Alcorn Green in Fishtoft at 10.22am on Saturday, where Roberts’ body was found in a common area at the rear of the street.
Speaking at the weekend, Det Supt Martyn Parker said: “This is a devastating incident in which a young boy has lost his life. The impact will no doubt be felt greatly in the community and beyond.
“This type of incident is not what we would expect to see within our communities. We are working with those affected to keep them informed and offer our support.
“I want to reassure the public that we will do all in our power to meticulously investigate the circumstances of this young boy’s death and we would urge anyone who has any information that could support this investigation to get in touch.”
