Daniel John Twigg has been named as the three-year-old killed in a dog attack in Greater Manchester on Sunday.
The little boy was rushed to hospital after paramedics were called to a property in Milnrow in Rochdale.
He died a short time later.
Inquiries by Greater Manchester Police have established the youngster was with a number of dogs in an outdoor area surrounding his home before he was discovered with serious injuries.
A 48-year-old man has been arrested under the Dangerous Dogs Act 1991 after he handed himself in to custody, police said.
He continues to be questioned.
Several dogs were seized and one, a Cane Corso, has been humanely destroyed.
Police are continuing to investigate “previous incidents involving dogs” at the same address at Carr Farm in Carr Lane.
Detective Chief Inspector Gina Brennand, said: “I send my condolences to Daniel’s loved ones. This is a heart-breaking time for them, and specially trained colleagues are supporting them.
“Though a man is in custody, our investigation is very much ongoing to establish the full circumstances surrounding this incident and ensure any criminal offences in relation to Sunday’s incident are identified and prosecutions sought.
“Meanwhile, officers are also reviewing other incidents of note. Due to previous contact, GMP’s Professional Standards Branch has referred the incident for review by the Independent Office for Police Conduct.
“We understand that this incident has had an impact on the community but we ask members of the public and the media to refrain from speculating whilst we complete our investigation and any subsequent proceedings are concluded.”
