A Kinder Surprise egg, full of crystal meth, was found by a six year old boy in Limavady, Co Derry.
The boy is said to have been playing with his brother when he found the egg, under a hedge.
It is reported that the boy passed the egg onto his father, who alerted the authorities to the illegal substance found in the egg.
Speaking to Newstalk Inspector Colin Shaw said: “This incident is of the uppermost concern for all of us.
"Tackling the use and supply of illegal drugs is a priority for us and the possibility that something so potentially dangerous has been discarded where children could find it is deeply concerning.
“I don’t want members of the local community to find drugs on their street, however, this incident just reminds us that criminals have no regard whatsoever for the safety of local residents, and I am thankful that this child had the sense to speak to an adult about what he discovered.”
