Teenagers are getting up at 5am to strip supermarket shelves of an energy drink created by two YouTubers.
PRIME Hydration was launched by social media influencers KSI and Logan Paul, and bottles have been selling out in minutes across Asda stores in the UK.
Shoppers have reported "madness in the aisles" as youths scramble to get hold of the £2 sports drinks as soon as new stocks arrive.
