Det Sgt Darren Cartwright said: “This was obviously a frightening experience for the boy’s parents, but fortunately he doesn’t seem to have been seriously harmed. It seems he had picked up a discarded paper wrap believed to have contained an illegal drug.
“There is potential for further for forensic investigation into the incident , and we would like to make parent’s, guardians, and caregivers aware of it, especially in light of the continuing hot weather which families are taking advantage of by visiting our parks and public areas."
