Boston pizzeria chain owner charged with assaulting, threatening immigrant employee

A Boston-area pizzeria chain owner has been arrested on federal charges that he physically assaulted and verbally abused an immigrant employee for a period of about 14 years, authorities announced Thursday. 

Stavros Papantoniadis, 47, was apprehended Thursday morning on one count of forced labor, the U.S. Attorney's Office for the District of Massachusetts reports. The Stash's Pizza owner, who goes by Steve, targeted undocumented workers and underpaid them, prosecutors said. 

In a statement, U.S. Attorney Rachael Rollins described the allegations against Papantoniadis as "horrific."
