An officer from the Creamfields Cops account said: "We have just arrested a suspect for attempting to bring the "Tesla - MDMA" pills we warned about earlier this week into the site.
"Please be very careful with anything you are offered and if you start to feel unwell make immediately to the First Aid on site."
Dubbed 'Blue Tesla' after the electric car manufacturer, the pill is a lethal cocktail of MDMA and cocaine which has been found in venues across London and Bristol.
However police have revealed that it has now been found in events in the North West, including Creamfields.
A 21-year-old died after taking ecstasy pills at a club in Tottenham in North London and the pill has been linked to another death in Bristol in July.
A spokesperson for Cheshire Police said: "We’ve been alerted to dangerous MDMA tablets, which are believed to be responsible for two deaths in the UK.
"Please remain vigilant and report to security if they see any of these at the event.
"You will not be judged if you or your friend(s) feel unwell so please always seek help if you need it."
