The bar Baretta posted about the incident on its Facebook page.
"On Saturday evening one of our female guests was injured. We understand that this was very distressing for her, and we're enormously upset that this has occurred in our venue," the post read.
"Assistance was rendered to the guest as soon as our staff were made aware of the incident. A senior member of our security team worked closely alongside an off-duty medic who was also in the venue at the time, and they worked to get the young woman comfortable."
Loose was then helped to an ambulance for further medical attention.
"After completing an investigation (via camera footage and statements) we confirm that at no time was the guest without assistance," the bar said.
"We appreciate there is a level of concern that we have not dealt with this incident appropriately, however this is absolutely not the case. The safety of our guests is ALWAYS our priority. We're very upset about what has happened to the young woman involved. We will continue to work through this with her and her family privately, not via social media."
