Dutch prosecutors are ramping up efforts to seize a staggering $253 million in assets linked to Europe’s most wanted drug trafficker — a man believed to be hiding in Sierra Leone.

Jos Leijdekkers, widely known by his underworld alias “Bolle Jos”, has become a notorious figure across Europe. Accused of trafficking massive quantities of cocaine, the 33-year-old fugitive is said to have accumulated a fortune from his criminal empire, including luxury items, gold, real estate, and even Bentleys.

Authorities allege that in less than a year, Leijdekkers earned around €114 million from 14 major cocaine shipments. In just six months, he reportedly used €47 million to buy nearly a ton of gold. His known assets include a hotel in Turkey, apartments in Dubai, high-end vehicles, designer bags, jewellery, and watches.

Prosecutors are now trying to confiscate everything.

Leijdekkers has already been sentenced in absentia in multiple countries. In June 2024, a court in Rotterdam handed him 24 years in prison for smuggling seven tonnes of cocaine, committing armed robbery in Finland, and ordering a murder. Belgium followed with a 10-year sentence in September for trafficking and assault. He was also linked to the chilling 2019 disappearance of Naima Jilal, a Dutch-Moroccan woman believed to have been tortured and killed.

His name surfaced in Sierra Leone after Dutch media discovered videos and photos online, posted by the wife of Sierra Leone’s President, Julius Maada Bio. To everyone's surprise, Leijdekkers appeared in a New Year’s Eve church service in Freetown, seated just two rows behind the President and beside his daughter, Agnes Bio, rumored to be romantically involved with him.

The footage sparked outrage and confusion.

Sierra Leonean authorities initially denied any knowledge of Leijdekkers’ presence. Later, Inspector General of Police William Fayia Sellu told reporters that their investigations led to identifying the man as “Umar Sherif,” but despite searching thoroughly and checking immigration records, they found no trace of his entry or exit from the country.

Even without an extradition treaty between Sierra Leone and The Netherlands, Dutch officials have submitted an extradition request, hoping to bring him to justice.

Meanwhile, in February 2025, Belgium again sentenced Leijdekkers to 13 more years in prison for orchestrating a failed attempt to reclaim 10 tonnes of confiscated cocaine from a customs warehouse. Belgian law enforcement arrested 20 individuals in connection with the plan — most of whom now face lengthy prison terms.

As for Leijdekkers, he remains in hiding — and for now, the man known as Bolle Jos continues to elude capture.
