Heavy security as Flor Bressers, 39, appears in Brussels court where 30 suspected accomplices will also be tried

The alleged head of a large cocaine-smuggling operation, who was one of Europe’s most wanted men at the time of his arrest, has gone on trial in Brussels.

Flor Bressers, 39, was flanked by heavily armed security officers when he arrived at the courtroom on Monday, dressed in a sharp suit and with slicked-back hair.

He is alleged to have jointly led a network that imported massive quantities of cocaine into Europe from South America, and will be tried alongside more than 30 alleged accomplices, including a Dutch lawyer and a former London banker.

Bressers is alleged to have earned €230m (£199m) from 10 cocaine shipments, while a second alleged ringleader, Sérgio Roberto de Carvalho, a Brazilian in his 60s, is alleged to have netted about €200m.
