Five of the seven teenagers involved in a suspected mass overdose at Saint Stephens College yesterday remain in hospital in serious or critical conditions, while two have since been discharged.
Headmaster Dr Jamie Dorrington released a statement on the school's Facebook page, that has been provided to parents and staff today, revealing that two others are showing signs of improvement.
Speaking to the media this morning, police said they believe the boys consumed a powdered substance several times throughout the day, some taking more than others. They are still waiting for toxicology results to confirm what the powder was.
Despite reports the group had shared videos on social media before and after taking the drugs, police have said they haven't seen any evidence of this.
They are however appealing for anyone who may have photos or videos of the incident to provide footage to police, but not send it on to anyone else.
Yesterday, two crime scenes were established at the school, on Reserve Road in Upper Coomera, with detectives seizing a number of mobile phones and electronic devices.
The Queensland Police Service taking the opportunity to remind the public that all illicit drugs are dangerous, regardless of how they are sold or what you've been told.
Anyone with information should contact Policelink on 131 444 or Crime Stoppers on 1800 333 000.
