Kevin Davies, 53, was caught out and exposed as a conman after his company, Pioneer Medical Solutions, was contracted by the company which organised an illegal rave at the former Royal Mail sorting office in East Croydon in 2014.

Astonishingly, more than 40 fake profiles are thought to have been set up on dating sites and social media by people stealing his image alone in order to attract women.

Some succumbed to pressure to send explicit photographs of themselves, with one woman left feeling ashamed and devastated after realising she had been betrayed.

Rio, from west London, died on June 16 from multiple organ failure and acute drug toxicity with his family by his bedside at Great Ormond Street Hospital.

The Metropolitan Police said a full investigation was carried out into Rio's death and, based on the evidence at the time, there was no criminal case to answer.

When the company folded in 2015 after it stopped becoming profitable in the aftermath of the rave, Mr How found out that Davies was lying about his qualification.

Lewis Edwards, prosecuting at Croydon Crown Court, said at his trial earlier this month that Mr How would 'never have invested in the business had he known Davies was not qualified'.However, the documents were analysed by the head of education for the West Midlands Ambulance Service Trust and both turned out to be fraudulent.Davies's two colleagues, who had paid to train with him, said they were both working under his supervision as they believed he was a qualified ICHD ambulance technician.At the time of the illegal rave, Davies had signed off more than 1,000 hours of their work-based assessments - which could not be validated because he was not qualified.Davies forged a certificate saying he was an IHCD-certified ambulance technician in order to secure a £32,000 investment in his business from Richard How, Croydon Crown Court heard on January 12.The 15-year-old was one of thousands of people at the rave in the derelict Royal Mail sorting office, in Cherry Orchard Road, on June 14, 2014.
