Police in Rugby are issuing a drugs warning after a boy was taken critically ill in the town.
It is thought the 16 year old had taken high-purity ecstasy before being found collapsed in Bilton Road on New Year's Eve.
Officers are investigating what happened - and say it's a stark reminder of the dangers of illegal drugs.
The boy, who is from Rugby, was discovered by a member of the public.
The member of the public flagged down a passing police car and officers administered first aid until paramedics arrived.
Police seized ecstasy from the scene and sent it away for testing.
Detective Inspector Dave Andrews said: "While it is too early to speculate on the circumstances leading up to the boy falling ill it is important to remind people of the dangers of taking illegal drugs. We strongly advise anyone to consider the consequences of taking any illegal substance; both in terms of their health and the legal consequences.
"We're particularly concerned in this case because of the discovery of high-purity ecstasy. I would urge anyone with ecstasy matching the description of that seized not to take it.
"We have launched a thorough investigation to establish the circumstances leading up to the boy being taken ill and whether any criminal actions contributed to his condition."
