A young woman says she was drugged and left suffering multiple seizures after reportedly being stabbed with a needle during a concert.

The incident is alleged to have happened at the Worried About Henry gig at Dreamland in Margate, with Gracie Warren sharing news of her ordeal on Facebook.

Police have confirmed an investigation has been launched after a teenage girl at the gig reported finding a puncture wound in her arm having fallen ill.

A spokesman said the report was made today following a separate report made yesterday by a woman who suspected her drink was spiked at the event on Saturday.

In a warning to others, Gracie wrote on social media: “People who were at the Worried About Henry Dreamland event last night and think they were just very drunk but didn’t drink a lot or passed out randomly please check your body for a small stab mark.

“I got spiked last night and ended up being blue-lighted to hospital.”

Gracie’s father, Mark, has also posted on Facebook about the incident, adding: “She lost all feeling in her arms and legs and started to foam at the mouth. She was then taken to the medical tent by a friend and family member, at which point she was totally unresponsive.”

Gracie says she suffered eight seizures and was kept on a four-hour drip “to flush the drug out of me”.

She left the hospital at 1.30am after undergoing a CT scan.

Her dad wrote: “Gracie was not on her own at any point and was with her boyfriend and friends at the time of the incident, which is what is so concerning.

“As a family we can’t thank the ambulance crew and hospital staff enough for the excellent care and treatment that Gracie received. Thank God she is finally feeling better today.”

Police confirmed today, a needle spiking report had been made after “a teenage girl had become unwell” and later “discovered a puncture wound on her arm” following the earlier drink spiking report on Sunday morning.

They earlier said a woman contacted them to report “she may have had her drink spiked at Dreamland, Margate the previous evening”.

Officers have since been in contact with the woman and inquiries to establish the full circumstances surrounding the incident are ongoing.

A spokesperson for Dreamland said: “On Saturday night two people were taken to hospital from Dreamland Margate where the Worried About Henry event was taking place.

“One patient showed symptoms in line with those of drug use. We understand that the patient has subsequently recovered. The other patient was suffering from non drug-related symptoms of a pre-existing medical condition.

“Dreamland staff and medical teams worked closely on the night to ensure that the patients were given the best on-site care and transferred them to the local hospital in a timely and safe manner.

“We take the health and safety of our customers extremely seriously, and should local Kent Police or medical staff see any requirement for any further investigations we will of course cooperate fully.”
