These are the terrifying moments a teenage girl appears 'possessed' after her drink was spiked in a nightclub by a mystery man.

Millie Taplin's body was left suffering horrific 'Exorcist-like' seizures and her hands left gripping like claws due to the effects of an unknown drug slipped into her drink.

The horrific footage of the 18-year-old in her hospital bed was released by her mum as a warning to other teenage girls.

Distraught mum Claire, 48, is seen in the video comforting her daughter as she lay contorting and unable to control her legs and hands.

Claire said: "I've never seen anything like it. Millie was aware of what was happening but couldn't speak.

"It was horrendous, she looked possessed."

Millie believes that her drink was spiked by a man who had been talking to her earlier in the night and had brought two drinks back from the bar at Moo Moos nightclub in Southend, Essex.

She had gone out drinking on Saturday night.

Claire said: "Millie only took two sips of the drink, we're lucky it wasn't any more.

"She felt sick almost immediately and went outside. She knew she wasn't drunk but was slumped in a nearby alleyway.

"I'm so thankful her friends were there for her, otherwise who knows what would have happened."

"There are no words for what I could say to the person responsible.

"She was really excited about going out on Saturday, she was so happy. It's such a shame."

Police have confirmed that they are investigating the incident.

Millie was discharged home after being held in overnight.

A spokesman for Moo Moos nightclub said: "We urge all customers to be present when their drink is ordered and that they do not leave it unattended.

"The alleged drink spiked appears to have been accepted from a person known to the lady affected and whilst it was not reported to us at the time, we are assisting the police who are dealing with the matter.”
