Chicago police say crime in the city has decreased from 2016

(CNN) The Chicago Police Department and Department of Justice's Bureau of Alcohol, Tobacco, Firearms and Explosives announced at a press conference Friday a new task force aimed at decreasing the spread of illegal guns throughout the Windy City.

CNN was first to report earlier this year the formation of the team, which the ATF called in internal documents the "Chicago Crime Gun Strike Force."

The team includes an additional 20 ATF agents, who arrived June 1, according to a city official, as well as 12 Chicago police officers, two Illinois state troopers, six intelligence analysts and state and federal prosecutors.
