The pub in Summerston was stripped of its licence after officers said it was, "operating in a manner likely to cause serious harm to the public".

Glasgow Licensing Board revoked the Gorstan Street pub's licence with immediate effect after a formal request from police who have been visiting the pub over the last 18 months.

A police report to the board said the pub was, "allowing the continued use of controlled drugs within the premises."

It added: "The management of the premises have been spoken to over a considerable period of time and made fully aware of ongoing issues in respect of drug misuse within their premises.

"The premises have taken little by way of steps to resolve the issue."

The report said: "There have been a considerable number of incidents relating to disorder linked to the premises where the staff members have been unwilling to fully assist police inquiries."

Inspector Duncan Evans said the pub's drug problem "represents the biggest problem to the area and to the community".

The Scotch - which is next to an Asda superstore - is owned by pub chain Trust Inns Limited, leased by Gerald Reilly and managed run by Margaret Burbridge.

The police report detailed visits over a year and attempts to convince managers to act.

It states that on one occasion, last August, officers found two men in the toilets, one of whom dropped four bags of white powder.

At last week's licensing board meeting, Joanna Brynes, a solicitor representing The Scotch said it has made efforts to counter drug-taking and including barring customers found with drugs - four so far.

She said managers staff checked bathrooms every 14 minutes, had removed toilet seatcovers, put wooden slats over cisterns and covered all surfaces with baby oil to stop users snorting from them.

Ms Brynes added: "Short of standing in the toilet cubicles there is not much more the licence-holder can do.

"They have genuinely tried every suggestion put to them and gone down additional avenues … they are reporting incidents and co-operating with the police.

"This is no drug den… if you went into other]premises in Maryhill or the city centre you'd find that people have been taking drugs … if you went into [other] premises in Maryhill or the city centre you would find that people have been taking drugs."
