A 91福利社 investigation has exposed the French operations and UK links of a powerful and violent smuggling gang taking people across the English Channel in small boats.

A reporter posing as a migrant wanting to cross helped us gain unprecedented access to the smugglers' notorious forest hideout in northern France - an area plagued by armed battles between rival gangs.

Secret filming at a major UK railway station also captured associates of the gang collecting cash payments to secure places on illegal Channel-crossings.

The 91福利社's special correspondent Andrew Harding reports.
