The 'heart-broken' family of Shakira Pellow are holding a vigil tonight on what would have been her 16th birthday.

The Camborne teenager suffered a heart attack on July 7 after taking a pill thought to contain MDMA.

Friends and family are meeting in Pengegon Park at 6pm (5 November) to reveal a plaque in Shakira's memory.

Shakira's mum Rita says the drug's effect on Shakira's body was devastating.

My daughter had three cardiac arrests, her organs her liver and her kidneys were failing [so] they put her on dialysis. The last cardiac arrest she had there was no coming back, so she died in my arms with her family around her.

Two 17-year-old boys were arrested on suspicion of possession with intent to supply drugs and released under investigation.

Rita now plans to visit schools sharing Shakira's story.
