A total of 76 firearms were seized and 405 arrests were made thanks to a joint effort by more than a dozen law enforcement agencies in Northern New Jersey.
The State Attorney General's Office, which spearheaded the operation, made the announcement Wednesday morning, according to The Star-Ledger.
The seven-month-long Passaic River Corridor Initiative began in May after state investigators examined out-of-state gun pipelines that often ended in Newark, Paterson and other cities in the northern part of the state.
"The common theme in both the Passaic River Corridor Initiative and our statewide strategy to fight gun trafficking is that we're partnering across all levels of law enforcement and sharing intelligence to proactively target career criminals, particularly the ones who are bringing guns and gun violence into our communities," Attorney General Jeffrey Chiesea said in a statement. "Each gun we seize potentially is a life saved.
The initiative focused mainly on gun trafficking. Investigators were able to capture gun distributors as they traveled from Georgia, South Carolina or Pennsylvania into Newark Penn Station.
Police have been able to link the seized weapons to other crimes through ballistics testing.
