Authorities would not comment on how those arrested were connected, but several are charged with conspiracy.
The home of Luis Ramos on the 2000 block of East Atlantic Street in Kensington was allegedly at the center of a gun-selling operation between February 2011 and this August. Memeger said Ramos, 34, was part of what he called the most brazen sale during the investigation, where buyers pulled up to Ramos' home or another location and, on at least 15 occasions, had a gun delivered to their car window.
Ramos and six others were charged with illegally selling 43 guns, plus ammunition.
In another trafficking case, which alleges 11 illegal gun sales between April and June 2012, an indictment charges Alexander Rivera-Matos, 21, of Philadelphia; Warren Johnson, 32, of Philadelphia; and Delano Bullock, 30, of South Carolina. Authorities said this ring operated in Kensington, out of the 1400 block of Jerome Street and an apartment in the 3500 block of Frankford Avenue.
In a third case, authorities charged Perry Leach, 36, of Philadelphia, with traveling in September 2010 from his then-home in Ohio to Philadelphia with firearms he intended to sell. Leach allegedly sold six guns illegally, plus ammunition.
The seized firearms will be entered into a database so they can be tracked, although officials would not comment on whether they suspected any were used in a crime. Several firearms were found with the serial numbers removed.
The indictments are the result of an undercover operation through the Violent Crime Reduction Partnership, which combines the resources of the Philadelphia Police Department, the U.S. Attorney's Office in Philadelphia, and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
"Law enforcement will continue to work together to take back our neighborhoods," Sheree L. Mixell, ATF special agent-in-charge, said at Thursday's news conference.
More than 170 Philadelphia and ATF officers participated in the operation. Deputy Police Commissioner William Blackburn said from 4,000 to 5,000 firearms are seized annually in Philadelphia.
The charges against those arrested carry a minimum penalty of five to 10 years in prison. Defendants with prior felonies could face life sentences if convicted.
