India, Feb. 22 -- Q uentin Griffiths, co-founder of online fashion giant ASOS, has died after falling from a high-rise apartment balcony in Thailand. According to The Sun, the 58-year-old reportedly fell from the 17th floor of an apartment in Pattaya. Police and paramedics later found him on the ground below his balcony. Authorities said there were no immediate signs of disturbance inside the apartment, but foul play has not been ruled out. The exact cause of death will be confirmed after a post-mortem examination. A source close to the family described the circumstances as unclear. "It's a real mystery. The phrase 'suspicious circumstances' has been used but we just don't know yet," the person told The Sun. Griffiths co-founded ASOS in 2000 with Nick Robertson and Andrew Regan. The company grew into a £3 billion global fashion retailer, with high-profile figures including the Princess of Wales and Michelle Obama known to have worn its designs. The death comes months after a dispute with Griffiths' Thai ex-wife, who accused him of stealing £500,000 from a company they operated together. He was arrested last year after she alleged he had forged documents to sell land and company shares without her knowledge. HTC...
