The sudden death of a 19-year-old man has led to a police warning over the dangers of a triple-strength blue ecstasy pill known as the 'punisher'.

Harley Girven, also known as Harley Mason, was found dead by police at his flat in Pomona Road, Shanklin, Isle of Wight, on Saturday.

In a separate case, warnings were also issued after five teenage boys were taken to hospital in the early hours of Sunday in Stratford-upon-Avon in Warwickshire after taking a batch of super-strength ecstasy known as 'Mandy'.

The sudden death of a 19-year-old man has led to a police warning over the dangers of a triple-strength blue ecstasy pill known as the 'punisher'. Harley Girven, also known as Harley Mason, was found dead by police at his flat in Pomona Road, Shanklin, Isle of Wight, on Saturday

Although Hampshire Police said the death of Mr Girven - a wheelchair user - was unexplained, they issued a stark warning about the dangers of the 'punisher' pill.

A spokesman said: 'As a consequence of the teenager's death, police are reminding people of the dangers of taking illegal drugs and in particular a blue triangular ecstasy/MDMA tablet known as 'punisher', which is known to be around three times stronger than other ecstasy tablets.'

The spokesman continued: 'Two other people who were in the flat when police and ambulance staff arrived were arrested on suspicion of possession with intent to supply class A and B drugs.

'They are a 16-year-old girl from East Cowes and a 17-year-old boy from Newport.

'They have since been released under investigation. Their arrests are not directly connected with the death.'

The spokesman said that a Home Office post-mortem examination would be carried out on Wednesday to establish a cause of death.

Mr Girven's family have paid tribute to him, saying: 'Our boy Harley; a fun and lovable son, grandson, nephew, cousin and friend to so many.

'We will remember you for your sharp sense of humour and unique take on the world, that sought to challenge you in so many ways, that others may never know.

'A courageous man with love in your heart, who will always be so much to so many.

Warwickshire Police warned others of the dangers of taking the drug.

Detective Inspector Lisa Sears said: 'We believe they have taken a type of MDMA known as 'Mandy'.

'At this time we are keeping an open mind as to whether this is a bad batch of drugs or an overdose.

'We are contacting Public Health for further advice.

'In the meantime we would urge drug users to be cautious and if you have taken this drug in the last few days consider seeking medical advice.'
