A police investigation is underway after a Hampshire woman collapsed and started fitting after being 'duped' into using a vape at Isle of Wight Festival.

A post on social media said Chloe Hammerton, from Southampton, was in and out of consciousness, fitting and unable to move or speak, within a minute of taking a puff of the vape.

Her partner Natasha Ward, from Winchester, said it was "one of the worst 24 hours of her life".

It was reported that Chloe, 26, was offered a vape by a man who approached her and her brother at the festival on Saturday, June 17.

Natasha said Chloe, who doesn't smoke or do drugs, was 'duped' into taking a puff. This was enough to make her seriously unwell. She said she suspects the vape was either spiked or drugged.

A picture shared with the County Press, the Chronicle's sister paper, by Natasha to raise awareness, shows Chloe collapsed on the ground.

Hampshire police have confirmed it is investigating.

A spokesperson said: "Officers are in contact with the woman and will be carrying out drugs testing to help further the investigation."

Natasha also raised concerns about the medical response given to Chloe following the incident.

She claims there was a 'lack of urgency' from medics.

The festival told the County Press a medical practitioner was on-site within five minutes and the incident was dealt with 'quickly and professionally'.

A spokesperson said: "We operate a zero tolerance policy for anyone attempting to bring drugs to the festival and have robust systems in place to deal with anyone who attempts to do so.

"This was an isolated incident dealt with quickly and professionally by all teams on site and no further reports of this nature have been recorded.

"Our event medical team employs a wide range of appropriately qualified healthcare professionals. These fully-trained individuals work 24 hours a day across our medical facilities on site.

"Regarding the incident reported on social media, we are confident the team dealt with it in a timely manner, with an appropriate medical practitioner on site within five minutes and the patient’s condition assessed as non-life-threatening and subsequently transported to the on-site hospital.

"The safety and wellbeing of attendees is our utmost priority and alongside our partners in the police, security and medical teams, we work incredibly hard over the festival weekend to ensure everyone is looked after."

Natasha said Chloe is feeling much better physically, but the incident has left her traumatised.
