The son of late Mango founder Isak Andic was arrested in Spain on Tuesday in connection with the fashion tycoon’s mysterious 2024 death after he plunged from a cliff while the pair were out hiking.

The billionaire’s son, Jonathan Andic — who took over the global fashion empire with his sisters after their dad’s death — was detained for questioning in Barcelona as part of the possible homicide probe, local cops said.

A spokesperson for the family confirmed the younger Andic, 45, was being questioned by investigators but refused to give further details.

The 71-year-old Spanish billionaire died after falling more than 320 feet in the Montserrat caves near Barcelona in December 2024 while hiking with his son.

Authorities initially described the fashion powerhouse’s death as an accident.

Nearly a year later, local media started reporting that Andic’s son was being officially probed as a suspect due to the contradictory statements he gave to cops when the tragedy occurred.

Jonathan, who was the sole witness, had told cops he’d been walking just ahead of his father on the narrow Les Feixades trail — a route that is often frequented by families and one authorities described as “not especially dangerous.”  

He said he turned to see his father suddenly falling off the edge of the path when he heard stones falling.

Police sources, however, told local outlets that the son’s version of events possibly didn’t align with the forensic evidence.

The Andic family has said it’s confident Jonathan is innocent.

Andic, who founded Mango back in 1984, was worth roughly $4.5 billion when he died — making him one of Spain’s wealthiest people.

His son and two daughters took over the business in the wake of his demise.
