Following the tragic drug-related deaths of two young people at Mutiny Festival in Portsmouth over the weekend, festival organisers are now issuing warnings to revellers about a batch of 'very strong' pills currently circulating the country.
Manchester's Parklife Festival - which takes place in June - tweeted this morning to ask people to 'act responsibly' and 'look after each other'.
Last weekend's Love Saves the Day Festival in Bristol also issued drug warnings relating to blue 'Punisher' pills and silver bar tablets, which have 'highly variable MDMA content'.
Another tweet from the festival alerted people to a pink heart pill being sold as ecstasy, which actually contained a high dose of an 'unpleasant, long-lasting stimulant'.
The mother of 18-year-old Georgia Jones, who was one of the two people to die after taking pills at Mutiny Festival, took to social media to discourage others from meeting the same fate.
Janine Milburn said: "I can now say Georgia died yesterday due to complications after taking two pills at Mutiny.
"If nothing else, I hope what has happened to her will deter you from taking anything ever."
The post, which has been shared more than 13,000 times, continued to say that the pills had caused her temperature to rise so high it made her fit.
She added: "My little girl was 18 and full of life, I just hope this stops at least some of you from ending up the same."

The second fatality of the festival was 20-year-old Tommy Bakeer, whose friends have paid tribute to him on social media - with one writing: "I can't believe you've been taken this soon we had some amazing times mate I'll get all of uniform services together for you man fly high up there bruv, gonna miss you."
A statement issued by the festival, on what was due to be its second day, said: "Following the terrible news from earlier today, the team behind Mutiny Festival are incredibly sad to announce that the Sunday of the festival has been cancelled as a safety precaution.
"The safety of our amazing customers has always been paramount to us and so to keep everyone safe and in respect to those who have passed, we have taken the decision not to open today. As you can imagine, this decision was not taken lightly and was taken with the support of the local statutory authorities who we continue to work with.
"Enquiries are being made into the circumstances of what has happened, but we must reiterate our advice to all our customers to responsibly dispose of any substances.
"More information will follow when available, we appreciate your understanding at this difficult time."
