ringleader

There is a risk that smuggling networks are replaced the moment some ringleaders are arrested.

Seven of them were arrested Germany, while Jörg S - the group's suspected ringleader - was arrested in Poland.

Writing about the Knicks bar also taught me that, beyond the owners, these places have to have some sort of ringleader.

The suspected ringleader, a 40-year-old Russian national, would also be charged, prosecutors said.

Although the ringleader was eventually sentenced to more than 40 years in jail, no action was taken against the platform, because of fears around censorship.
