More than a dozen foreign nationals in Milwaukee have been arrested for alleged ties to the Mexican Posse gang, the Milwaukee Journal Sentinel reports.

The suspects – 13 from Mexico, one from the Dominican Republic – are in the custody of the U.S. Immigration and Customs Enforcement, which is cracking down on foreign-born gangs.

All have criminal histories, ranging from narcotics trafficking to theft.

“Violent street gangs account for a burgeoning amount of crime in our communities in the Midwest and across the country,” Gary Hartwig, special agent in charge of Homeland Security Investigations, told the Journal Sentinel.
