ONE of Scotland's most glitzy and celebrity-laden nightclubs has been banned from selling alcohol after police accused door stewards of beating a reveller unconscious.

The glamorous One-Up venue in Glasgow is a regular haunt of high-profile footballers and actors but licensing chiefs have called time on the club until they are satisfied staff have completed conflict management training among other requirements.

It is unclear how long the ban will last but it is understood the night spot - owned by the family of licensed trade kingpin James Mortimer - will be shut for days, if not weeks.

Police claim three door stewards left a male customer unconscious following after a closing time row before dragging him down a flight of stairs and leaving him in the street.

The incident has led to one of the stewards facing assault charges and another charged with assault and working without the required licence.

The altercation allegedly broke out when one of the stewards removed a drink from the customer, sparking a scuffle.

Police claim the customer was forced to the floor with three stewards sitting on him. 

Superintendent Carle said: “At 3.09am the male ceases moving and appears to be rendered unconscious.”

He said two stewards then took hold of the man being restrained on the ground by each wrist and dragged him toward an exit, still apparently unconscious.

It is alleged that the stewards then began “dragging the male down 25 steps before being dragged out of the premises’ main exit and discarded on the pavement, lying on his back, during which he continues to appear unresponsive”.

Superintendent Carle also said another male customer is seen on the CCTV being “forcibly ejected...narrowly missing the unconscious male and police officers tending to him”.

The man was taken to the Glasgow Royal Infirmary and did not regain consciousness until two hours later.

The police also led evidence on a number of other unrelated incidents, including one on the same night in February when a customer was knocked unconscious after being punched by another male. the man responsible has not been traced by police.

And in another incident in June 2015 a customer lost consciousness after being struck with an ice bucket by another man, who has also not been traced.

Police attending said the crime scene had not been preserved by One-Up’s management. 

Lynnet Leisure’s lawyer Archie Maciver said all four of the stewards accused of involvement had been sacked.

He added that since the incident measures introduced included checks of stewards against the Security Industry Authority website; automatically checking incidents against CCTV footage; and that all staff must report any incident directly to the premises manager.

He said part of the retraining included showing all staff CCTV footage of the incident.
