A woman says she was spiked by injection but had dismissed it as being a cut.
Chloe Madico, 20, went out for a pal's birthday to Popworld on October 23 in Guilford, Surrey where she said she was surrounded by school friends the entire night.
Chloe was shocked when she woke up the next morning with a mark on her leg and realising she couldn't remember a huge part of the night, SurreyLive reports.
She said: "I have no recollection of the night whatsoever, my friend had to tell me a lot of the stuff that happened.
"I just assumed I was just really drunk, even though I'd never experienced anything like that. I was apparently dead weight, I was falling to the floor, I couldn't string a sentence together."

Chloe added: "When we saw the mark on my leg in the morning, we just assumed I had cut myself."
When she returned to Bournemouth, where she now lives, her flatmates said they saw similar marks on social media with reports of others being injected.
She continued: "At first as I was just 'oh it will be fine' but my flatmate was insisting I go to the hospital."
Nurses and doctors at Royal Bournemouth Hospital confirmed it looked like an injection mark.

Chloe says now she needs to get multiple blood tests, vaccinations and trips to the hospital and a sexual health clinic to make sure she has not caught anything from the needle that spiked her.
Chloe's ordeal comes as police forces around the UK have received a growing number of reports of people being spiked in bars and nightclubs around the country, with some allegedly being targeted with needle injections.
The increase in reports and accounts has led to some institutions ramping up their efforts to keep patrons safe.

Some pubs have installed led 'airport-style' security at the doors and others have scrapped 'ladies' night' over safety concerns.
The spiking reports also led to a national movement to boycott clubs, which was organised by university students.
Chloe now hopes to raise awareness for anyone to see medical attention as soon as they can.
She continued: "The only reason I went to hospital was because a girl I lived with sent me a social media post - I just thought it was a cut and kept saying I would be fine.
"If she hadn't convinced me, I would have been sat here thinking it was a cut on my leg. I was so shocked at the time I had no idea, that's why I didn't go straight to A&E. Looking back now I know I definitely needed to."
Chloe says that although she felt safe going out she believes establishments could make improvements to make it safer.
She said: "No disrespect to Popworld, but they could've done more on entry. I know it's hard to bag search everyone but they were just doing spot checks rather than everyone.
"I know it might take longer to get people in and it could cause bigger queues but I do think they need to up their game."
A spokesperson for Popworld said: "The safety of our guests and our team, has always been, and remains our number one priority and we continually review our safety and security procedures to ensure our customers and staff remain safe.
"We treat all allegations of spiking seriously and ask customers to bring this to our attention immediately should they have concerns their drinks have been tampered with.
“We are aware there is increasing concern over alleged increases in spiking in clubs and bars and have therefore enhanced our measures and employed Guest Support to assist any guests that are feeling vulnerable or unwell.
"These team members are easily identifiable, as they wear a neon armband. We have enhanced security checks on our door, and we ask guests to remain vigilant and report any unusual or suspicious behaviour to one of our team immediately."
A Surrey Police spokesperson added: "We received a report of spiking by injection over the weekend commencing Friday, October 22. The victim is receiving ongoing medical care and support from family and friends.
"This is the first such report of needle spiking that we have received in Guildford, although we do occasionally receive reports of drink spiking. Our Divisional Drugs Liaison Officers and Licensing Officers work closely with nightclubs and bars to raise awareness of this issue, including giving advice to the venue's staff on how to recognise the signs in someone whose drink has been spiked, and what to do in that situation.
"We will continue to liaise and work with them in relation to this latest issue.
"We would encourage anyone who believes they have been a victim or witness to spiking, in any form, to contact their local police force as soon as possible. Any reports of spiking will be investigated and taken seriously."
