One man, who was in his thirties and from Chelmsford in Essex, died after taking what police believe to be an amphetamine-based drug, 5-EAPB, also known as Benzo Fury.
He was taken ill while at Brownstock Festival on Sunday (1 September), and he died that day at Basildon Hospital. The man’s girlfriend was also admitted to hospital and is still receiving treatment.
In a separate incident, another man who attended the three-day festival, in his thirties from Surrey, was thought to be walking along one of the country roads at around 10.45pm on Saturday (31 August) when he was hit by at least four cars.
In a statement released by the Brownstock Festival team, it said they are "devastated", adding: "Our thoughts and prayers are with the families and friends of those involved. Families have been informed by police.
"So shocking and sad, in all respects. Please be safe, not sorry."
This year's Brownstock Festival featured 12 stages and interactive areas hosting a line-up of music, comedy and entertainment including Professor Green, Tom Odell, The Fratellis, The Pigeon Detectives and a DJ set from Mark Ronson.
