A judge investigating the death of Mango founder Isak Andic has identified the billionaire's son as the prime suspect in the case, according to court proceedings.

Jonathan Andic, son of the Spanish fashion retail tycoon, has emerged as the focus of the investigation into his father's fatal fall. The judge overseeing the probe has cited concerns about the younger Andic's relationship with money as a factor in the case.

Isak Andic, who built Mango into a global fashion empire, died in what authorities are treating as a suspicious incident. The circumstances surrounding the billionaire's death have prompted a formal investigation by Spanish judicial authorities.

The case has drawn significant attention given Isak Andic's prominent position in the fashion retail industry. Mango, founded by the elder Andic, operates thousands of stores worldwide and represents one of Spain's most successful fashion brands.

Jonathan Andic has not publicly responded to the allegations. The investigation remains ongoing as authorities continue to examine the circumstances that led to his father's death.
