Chester County District Attorney Tom Hogan said the arrests were made during the third round of "Operation Silent Night."
All nine suspects have been charged with drug dealing, primarily in cocaine and heroin.
In a statement, Hogan said "A year ago, we unleashed Operation Silent Night in Coatesville. Working together, Chester County law enforcement took criminals off the street, developed hard intelligence on criminal organizations, and helped reduce violent crime in Coatesville. Operation Silent Night has been a success not just in solving crimes, but in preventing crimes."
Those arrested are:
