A 15-year-old boy remains in hospital a week after taking a suspected ecstasy tablet.
The Perth schoolboy was placed in a coma after taking a substance on Friday October 28.
He remains in a serious condition in Ninewells Hospital, but has been described as ‘stable’.
A 17-year-old boy had been charged in connection with the alleged incident.
Another 15-year-old boy from the Fair City was also hospitalised after consuming an unknown substance in an entirely unrelated incident. He has since been discharged.
Police Scotland has now issued a warning against taking unknown substances.
Chief Superintendent Paul Anderson said: “The dangers of taking drugs are real and clear for all to see. Quite simply, you can never be sure of what you are taking or how your body will react. It only takes one bad reaction to put your life in serious danger and it really is not worth the risk.
“We will continue to take action against those who supply illegal drugs in our communities and we will be working with partners in education and health to educate young people and the public about the risks involved.
“We do not want to see illegal drugs being dealt in our communities and I would urge anyone with information about drug dealing to contact us so we can take robust action.”
