Six 13-year-old children are in hospital after taking MDMA, police have said.
Police issued a warning after the teenagers were taken to Crosshouse Hospital in Kilmarnock, Scotland, after falling ill on Saturday evening.
Emergency services were called at about 6.25pm and police in Ayrshire said they believed the teenagers, who all knew each other, had taken a type of MDMA.
Detective Inspector Fraser Normansell, said: "Police were informed of six children who had been taken to Crosshouse Hospital after taking unwell.
"One line of enquiry is that they had taken a type of MDMA tablet, believed to be red, green or brown in colour bearing an owl logo.
"We want to remind the public that any drug can be dangerous and that you are putting your health at risk if you do take anything unknown to you.
"Anyone who feels unwell, or knows anyone who appears unwell after taking these substances should seek medical treatment as soon as possible."
