A 28-year-old woman from the Caerphilly area was arrested on suspicion of being in charge of a dog dangerously out of control causing injury resulting in death. She was later released on conditional bail.
Two men – a 34-year-old from the Mountain Ash area and a 19-year-old from the Caerphilly area – attended voluntarily in relation to an offence of being in charge of a dog dangerously out of control causing injury resulting in death. Both were later released.
Chief Superintendent Mark Hobrough said:
“The work to identify the breed of dog involved this attack continues.
“Once this is completed, we will be able to establish if the breed features on the list of illegal dogs to own in this country and any other criminal offences identified will be investigated fully by officers.
“I understand that there is a lot of interest about this in our communities.
“It is vital that people think about how their social media comments or posts could impact the ongoing investigation, and Jack's grieving family.
“Once again, my condolences and thoughts are with Jack’s family, friends, school friends and everyone affected by this within the community.”
