Tributes have been paid to a schoolgirl who died after collapsing at a Glasgow nightclub following a suspected drug incident.

Regane Lenaghan MacColl, 17, from Duntocher, Clydebank, became ill while inside the Arches in Glasgow on Saturday, and was rushed to the city's Royal Infirmary. She died in the early hours of Sunday.

Police said her death could be linked to red "mortal kombat" tablets, which have a red dragon logo stamped on them.

Officers have issued a warning about the tablets, which have been linked to four other people falling ill.

As part of a police investi­gation, a 19-year-old woman was arrested in Clydebank and charged with alleged drugs offences.

She has been released and is due to appear in court at a later date.

Ms MacColl was a sixth year pupil at St Peter The Apostle High, Clydebank.

Her family was too upset to speak about the tragedy, but Lawrence O'Neill, a local councillor, is a close friend of both Regane's parents.

Last night, on behalf of the family, he told The Herald: "Both Alastair and Vickie are thankful for the overwhelming goodwill gestures and condolences offered to them since the tragedy emerged. They would hope now that people will give the family time to grieve in peace.

"Both Alastair and Vickie and the wider family are absolutely devastated by this. It's one of those things that always happens to someone else and never you or your children.

"The two of them are shattered that this has happened to their daughter who really was a bright light in their lives and for her family and friends and those who knew her. That light has now gone out."

Regane's head teacher Linda Booth described the teenager as "popular, hard-working and enthusiastic".

Ms Booth said: "Everyone feels a deep sense of grief and our thoughts and prayers are with Regane's family and friends at this devastating time.

"She was a popular, hard-working and enthusiastic pupil and staff always found her to be pleasant and well-mannered.

"This is a real tragedy for a girl who worked so hard and I am sure would have gone on to achieve so much in her life."

Local people said they would support the family, including Ms MacColl's siblings, including brother Ben, and her mother Vickie Lenaghan.

Ms MacColl was described as "popular" and "bubbly".

A shop worker who knew Regane, but asked not to be named, said: "She was just lovely. The family will be devastated. She was so close to her mum.

"It will be a terrible loss to her family and the community. You just don't know what young people are up to nowadays.

"You tell them not to do things but sometimes they just do it."

West Dunbartonshire Council said it provided drug awareness education appropriate to the ages of its pupil.

Four other young people were hospitalised. A second woman, 19, and understood to be a university student, was admitted to the Royal Infirmary, but later discharged.

A further three men, aged 18, 18 and 26 were admitted to Crosshouse Hospital, Kilmarnock. One of the 18-year-olds was later transferred to Hairmyres Hospital, East Kilbride, where he is in a serious but stable condition. The other two men are still in Crosshouse Hospital.

It is understood Ms MacColl may also have taken other substances on the night that she died.

Police said it was still unclear what caused her death and a post mortem examination would be carried out.

Meanwhile, Neil McKeganey, director of the Centre for Drugs Misuse Research, said the fact young people were willing to take increasing numbers of drugs without any knowledge of what is in them was a major concern.

He said: "We are facing a ­situation even more serious that it has been in the past.

"A culture has developed where there is a willingness to pop a pill without any knowledge of what it is and what chemical compounds are within the drugs."
