A teenager has been arrested on suspicion of supplying class A drugs by police investigating the death of a boy found unconscious in a park.

Carson Price, from Hengoed, was discovered in Ystrad Mynach Park in South Wales at around 7.20pm on Friday.

The 13-year-old was pronounced dead after being taken to University Hospital of Wales in Cardiff, 12 miles away, and police have said they are treating his death as unexplained.

Officers raided a home in Pontllanfraith, Blackwood, this morning and arrested a 14-year-old boy on suspicion of supplying class A drugs.

He was taken into custody at Newport central police station and will be interviewed by detectives.

Detective Chief Inspector Alun Davies said: I would like to take the opportunity to thank the community who have assisted the investigation.

I would encourage anyone with any further information that may assist with our enquiries to make contact with Gwent Police and we will keep you updated with any further developments.

Paying tribute to Carson, his family said he was bright and caring, kind and loving, he was a cheeky little boy.

They added: He was the best big brother and was loved and will be missed by so many.

Friends of the family also expressed their shock and sadness, while Lewis School which the teenager attended in nearby Pengam said pupils and staff were devastated.

The school said in a statement on Facebook: At such an awful time I’m sure that everyone in our community will join with us in passing on our deepest condolences and sympathy to everyone touched by this tragic event.

Support will be made available to any pupils or staff in the weeks ahead but in the meantime our thoughts are with the family, we literally have no words.
