A 20-year-old man and 18-year-old woman tragically died yesterday at Mutiny Festival, no official cause of death has been given but the incidents came after reports of a 'bad' or 'super-strength' batch of drugs that were circulating around the festival.

The deaths are not being treated as suspicious by police and the victim's next-of-kin are being supported by specialist officers.

As a "safety precaution", Mutiny Festival organisers have decided to cancel the second day of the event amid concerns that more may have fallen victim and also as a mark of respect to those that lost their lives yesterday. A statement was released on Facebook by the organisers on Sunday morning confirming the cancellation:

Hampshire constabulary released their own statement on the incident that read: "At 7:10pm on Saturday 26 May, we were informed that an 18-year-old woman had fallen ill at the festival site in King George V Playing Fields, Cosham."

Within 20 minutes of the first incident, the man was later found collapsed at the festival. Both were rushed to Queen Alexandra Hospital, Portsmouth in critical condition where they later died.

At 21:30 BST, Mutiny Festivals released a statement urging attendees not to take any substances at the festival after reports of a dangerous batch of high-strength drugs was reported to be in circulation on-site.

Another festival-goer is reportedly also in critical condition at Queen Alexandra Hospital, Portsmouth while at least 15 others required treatment from substance-related incidents.

Mutiny Festival was also at the centre of controversy last year as Hampshire Police called for the minimum entry age of the festival amid to be increased to 18 claims of sexual assault, drug use and violence among festival-goers - there were reports of children as young as 13 in attendence. 

As well as the age limit increase, festival organisers had also introduced "revised entry procedures" in an effort to tackle criminal activity.

Despite this, some of yesterday's attendees reported security measures as lax, stating that searches were not as thorough as required. Security checks did not include pat-downs and bag checks were described as minimal.

30,000 revellers were headed to the festival in one of Portsmouth's biggest musical events, held on King George V Playing Field in Cosham. The electronic music event was scheduled to be two days of electronic music featuring a range of artists playing Garage, Drum 'n' Bass, RnB and Hip-Hop. Artists in attendence included Sean Paul, Dizzee Rascal and Craig David.
