Police investigating the tragic deaths of four young people have made an 11th arrest on suspicion of drugs-related offences.
Northumbria Police said inquiries were ongoing into the deaths of two 18-year-old women, who were found unresponsive over the weekend in the same Newcastle University student accommodation, and two men believed to have taken ecstasy elsewhere.
The women were first years who had been in the city for less than 48 hours, and were suspected of taking ketamine.
One of them was Jeni Larmour, described by her former school where she was deputy head girl, as a “model pupil”.
The Royal School in Armagh, Northern Ireland, said: “We have no doubt, that given her academic ability and personality, Jeni had a bright future ahead of her and we are saddened that has been so suddenly cut short.”
Ms Larmour’s mother worked at Ulster Carpets, a manufacturer in Co Armagh.
A company statement said: “This is a private family matter and our thoughts are with them at this distressing time.
“Sandra Larmour is a long-standing employee with Ulster Carpets.
“Her colleagues are shocked and deeply saddened by the news of her daughter Jeni and the Company will support Sandra in whatever way we can.”
Over the same weekend, an 18-year-old from Washington, Tyne and Wear – who was not a student, and a 21-year-old from Northumbria University died after they were suspected of separately taking MDMA.
Northumbria Police said officers would not be releasing any of the identities of the young people who died at this stage.
Police made 10 arrests for drugs-related offences over the weekend, and on Tuesday held a 30-year-old man on suspicion of supplying a Class A drug.
More searches of student blocks have been carried out by the police.
Chief inspector Steve Wykes urged any students who have illegal drugs to dispose of them safely, either by contacting a university welfare officer or by visiting their local police station.
He said: “We are all still in shock at what has been an incredibly sad and difficult weekend.
“Public safety is our absolute priority and we are working closely with our partners at the universities and in the local authorities to ensure all students and everyone living in our local communities are fully supported at this time.”
Anyone with information is asked to call 101.
