TWO young people are in hospital and three more are ill after ingesting capsules filled with an "unknown substance" at a school residence on Orkney.

Police have launched a joint investigation into the incident that occurred at the Papdale Halls of Residence which provides accommodation for Kirkwall Grammar School pupils who travel from outlying islands.

Five pupils took clear capsules containing an "unknown substance" which is thought to be a "brown or other coloured liquid".

The pupils fell ill on Wednesday, January 26 and two of the five were taken to hospital.

The details of the young people who have taken ill are not known but Papdale hosts pupils aged between 12 and 18-years-old.

It is understood that the condition of the two young people in hospital is not serious, however, police are liaising with NHS Orkney and Orkney Island Council (OIC) to establish the circumstances surrounding the incident.

A joint investigation is ongoing to establish the circumstances and the local authority are encouraging parents to speak with their children about the situation and hand over any remaining capsules.

An OIC spokesperson said: “We are asking for parental support to assist in dealing with this situation and want to stress that this is not about punishment, this is about the health and wellbeing of our young people at this time.

"We are appealing for parents and carers to ask their children if they have in their possession an unknown substance, in particular a clear capsule that may contain a brown or other coloured liquid.

"It is important that anyone with such a capsule hands it over to their parents, the school, an appropriate adult or the police and not to ingest it. It’s vital that we all work together to ensure our young people are made aware of the potential dangers of taking substances that they are not familiar with.

“A joint investigation is ongoing to establish the circumstances surrounding the incident and inquiries are ongoing.

“Anyone with such a capsule is urged to hands it over to their parents, the school, an appropriate adult or the police, and not to ingest it.”
