Mr Desmond was reportedly flown to nearby Adeje, where an ambulance was waiting to transport him to hospital, but he tragically died.
Friend Sacha Pugsley, 29, said the Cardiff resident was “very bubbly, very outgoing” and “always had a helping hand for everybody”.
She added: “He would literally walk the world for me if he could. He was always happy, always bubbly.
“I don’t think I’d ever seen a time where he was upset. He’d never bring anybody down.”
