A young woman was carried unconscious from a Canterbury bar after her drink was reportedly spiked with a date-rape drug.

The reveller was thought to have been celebrating a birthday with her friends in Alberrys in St Margaret's Street on Friday evening when she collapsed.

She was rushed to hospital by ambulance crews, said to be suffering from temporary paralysis and hallucinations.

Tests are later believed to have shown that her drink had been laced with a date-rape drug used by would-be attackers to incapacitate potential victims.

A warning has since been circulated on Facebook and shared more than 1,700 times.

Alberrys bosses confirmed on the social networking site that a woman collapsed in the toilets and they are working with authorities to "resolve the situation".

In a statement, they said: "Unfortunately a young lady had been found in the toilet by a member of our staff in a state that first presented as an overindulgence in alcohol.

"Initially her friends were reluctant to let our staff help and refused to let us move her to an area where we could assist the lady.

"When we were able to assist her it seemed to us she was suffering from more than just excessive alcohol, at which point an ambulance was called by the duty manager.

"The lady was taken to the K&C accompanied by a friend and we understand has thankfully now made a full recovery from her ordeal. All at Alberrys wish her well."

The post added that the bar has a "very strong" anti-drugs policy and a team of staff who take the issue seriously.

It continued: "We are currently reviewing all CCTV, and are hoping to speak to the lady concerned in the next day or so."

A post accusing bar and door staff of mishandling the incident has been shared more than 1,700 times on Facebook, but the venue's bosses strongly refute the claims.

Alberrys director Brendan Shilling later said: "I am pleased to report that I have spoken to the young lady involved in the incident on Friday night who has made a full recovery.

"We would like to stress that we are in no way inferring that the lady herself took drugs or was at fault in any way.

"She herself informs me she doesn't even know the person who made the post (on Facebook) and we are working with her and the authorities to ensure we resolve the situation."

South East Coast Ambulance Service spokesman Liz Spiers said: "We were called to this bar on Saturday at 12.45am to a woman who had collapsed.

"A responder and an ambulance was sent and the woman was taken to Kent and Canterbury Hospital."
