Merseyside school children in hospital over drugs
Ten children were treated in hospital after taking what is believed to be prescription drugs at school.
The alarm was raised by staff at St George of England school, Bootle, after a number of pupils began showing signs of drowsiness and sickness.
The pupils, all aged between 13 and 15, were later released from Alder Hey hospital with no long-lasting effects.
Two people - a 13-year-old girl and a 44-year-old woman - were arrested and have now been bailed by police.
Officers are investigating what the children took and where they got it from.
Supt Julie Cooke, of Merseyside Police, said: "The school were concerned because a number of the children had been presenting with signs of having taken some sort of drugs."
Ten children were taken to Alder Hey and later released.
"They were showing signs of drowsiness and sickness, but all of them have now been released with no residual symptoms," Supt Cooke added.
Ms Cooke revealed that about 12 other children were also checked over by ambulance staff called to the school.
Forensic examinations of the drug, which is believed to be Diazepam, will now be carried out.
"We are investigating the full circumstances around what has happened and how those drugs actually did enter the school, and how the pupils got hold of those drugs," she added.
