A 14-year-old boy, who was arrested on suspicion of supplying class A drugs following the death of Carson Price, has been bailed as police ''seek charging advice.''
The boy from the Blackwood area was released on Friday as Gwent Police seek advice from the Crown Prosecution Service.
13-year-old Carson Price, from Hengoed, died after being found unconscious in a park on the 12th of April.
He was taken to University Hospital of Wales in Cardiff where he was pronounced dead.
Tributes were paid to the teenager at a vigil on Thursday.
Gwent Police thanked the local community for their support and urged them not to post about the investigation on social media.
