Police have reported a man for alleged licensing offences and a number of people for drugs offences at the nightclub involved in the death last year of 17 year old Regane MacColl.

The teenager died in hospital in Glasgow after collapsing at The Arches in February 2014, after taking a suspect ecstasy tablet.

In the early hours of Sunday morning, police responded with other emergency services after a 30 year old woman was found unconscious in the street outside the club.

The woman, who was said by police to be heavily under the influence of alcohol, and believed to be under the influence of other substances, denied drug use to police. She was taken to Glasgow Royal Infirmary but later discharged herself.

Following the incident, police officers say a man has been reported to the procurator fiscal for alleged licensing offences, while several others are being reported for alleged drugs offences. The Arches - which was full for a GBX Anthems club night set by Radio Clyde DJ George Bowie - shut early, prompting dismay from those attending.

The Arches declined to comment in detail on the incident, as did Glasgow City Council, where licensing chiefs will receive a report of events on Monday.

However it is likely to raise fresh concerns about the licence of the popular venue. After the death of Ms MacColl the city's licensing board deliberated for four hours over its future after calls from Police for its licence to be reviewed.

Police Scotland had called for a review, arguing The Arches had breached conditions on preventing crime and disorder and securing public safety.

However the club said then that it had put in place fresh measures to prevent misuse of drugs on its premises, and was restricting admission to its club nights to over-21s and enhancing security, introducing new technology to spot face IDs, drug awareness teams, and 'calm time' during club nights. It is understood the age restriction has since been relaxed.

The licensing board concluded there were no grounds to review the venue's license and that there had been no failings by management on the night the teenager died.

Yesterday a spokeswoman for Police Scotland said: "We responded to a call at 12.40 saying that a woman was unconscious outside the Arches. Subsequently a man was reported for alleged licensing offences and several people were reported to the procurator fiscal for alleged drugs offences and at 2.45am the club was closed."

Both the 30 year old woman who collapsed - who had been in the club - and a significant number of those attending the event were severely inebriated and some appeared to be under the influence of other substances, she said.

A spokeswoman for Glasgow city council confirmed that licensing officials would expect to receive details of the incidents this morning (Monday), and said it would be inappropriate to comment further.

Confused party-goers on social media appeared unsure why they were being sent home and the Arches initially blamed the early closure on 'technical difficulties beyond our control'.

Subsequently on Facebook the club's press officer Georgia Riungu apologised to customers and said: "The decision to close early tonight was made in consultation with Police Scotland. We're closed today but management are investigating the situation and will have more information for you in due course."

In a statement, Ms Riungu added: "The Arches can confirm that, in consultation with Police Scotland on the night, Saturday's GBX club was closed earlier than advertised. We are not in a position to comment further until a full review of the circumstances has taken place."

The incident comes with the Scottish Parliament currently considering the Air Weapons and Licensing (Scotland) Bill, which includes measures requiring pubs, clubs and supermarkets to demonstrate how they will reduce consumption of alcohol in order to secure a licence.
