Karaoke bar customers carried on dancing as a paramedics fought to save a man's life, police have said.

Shane Cullen, 31, died after being assaulted at Blues Cabaret and Karaoke Bar on Bow Street, Ashton-under-Lyne, on 11 July.

Greater Manchester Police (GMP) told a Tameside Council licensing committee hearing that management did not shut off the music, stop alcohol sales, raise the lights or evacuate the premises "despite the severity of the situation".

Tameside Council suspended the venue's licence for three months and ordered it to abide by conditions including increasing security staff before it can re-open.

After the incident, GMP applied for a review of the bar's licence.

In a statement served ahead of the council licensing committee meeting on Thursday, PC Craig Foley said the force had serious concerns, including about "significant failings in management, supervision, compliance and leadership".

Foley said door supervisors outside had "no effective view" of events occurring inside.

A bouncer was also noted to have witnessed a separate assault outside the bar "without intervening or acting".

Foley said that officers attended the bar and helped clear a space for paramedics to begin commencing CPR.

He wrote: "Despite the severity of the situation, alcohol sales continued, music continued to be played and customers continued dancing and congregating around the area where officers were administering CPR.

"No member of management took control of the premises.

"The music was not stopped, the lights were not raised, alcohol sales were not ceased and customers were not evacuated.

"Police officers were ultimately required to clear the premises themselves to create a safe working environment for paramedics."

Foley raised concerns about a delay in providing full CCTV footage of the alleged attack owing to the premises supervisor not being on site.

"It delayed and hindered a live murder investigation," he said.

Foley said the combined problems identified amounted to "fundamental failures of management, supervision and leadership that contributed to an environment in which serious violence occurred and where the emergency response was subsequently hampered".

The bar's licence had been temporarily suspended in the wake of the incident but councillors decided to further suspend it for three months, allowing for a "full reset" of the business.

As part of the new set of licence conditions before it can re-open, the bar must also stop serving alcohol at 01:00, change its designated premises supervisor, introduce mandatory searching of customers and implement CCTV improvements.

In a tribute after his death, Cullen's mother said: "Shane was a big, gentle giant who wouldn't hurt anyone.

"He was a good dad, son and brother. He will be sadly missed."

Carl Cooper, 36, of Smallshaw Lane in Ashton-under-Lyne, has been charged with Cullen's murder and is due to stand trial in January next year.
