Secret Garden Party 'legal high' warning after Cambridge deaths

Officers cordoned off an area close the River Cam following the deaths

Festival-goers are being warned about "legal highs" after a homeless couple died in a suspected drugs-related incident in Cambridge last week.

It is thought Kim Reid and Jimmy Sinclair, who died on 16 July, may have taken an ecstasy substitute.

Cambridgeshire Police are expecting up to 30,000 people to attend the four-day Secret Garden Party in Abbots Ripton, which begins on Thursday.

A "zero tolerance approach" to drugs at the event would be taken, they said.

The exact cause of death of the pair - due to marry in September - has yet to be determined by a coroner.

However, officers suspect they may have been in a group of eight people thought to have used the same batch of an ecstasy substitute - PMA - on that day.

Similar "psychoactive" substances have also been linked to several deaths in Scotland.

A police spokesman said: "On occasions these substances can be as strong, if not stronger, than the substance they are trying to imitate."

Festival-goers have been warned security checks will be carried out by officers patrolling the Secret Garden Party site.

Motorists and residents in the Huntingdon area have been told to allow extra time for journeys.
