CHICAGO - The Chicago Police Department has launched a weekend crackdown on crime and drugs with a coalition of police department and federal agencies. Superintendent Eddie Johnson kicked off the joint operation Friday night with a press conference at Central and Madison. Johnson says CPD will be working with the Cook County Sheriff's Department, the FBI, DEA, Department of Homeland Security and the Illinois State Police to break up gangs in "hot zones" on the city's West and South sides. Johnson says the crackdown is meant to send a message to gang members and criminals that crime is not tolerated.

Johnson helped arrest three suspects in a carjacking Friday night, just before he spoke with media. Officers were following a Lexus sedan that was reported stolen in Cicero. After a brief chase, the car crashed near Quincy Street and Laramie Avenue on the West Side. The driver took off on foot, but officers caught up with him. They also arrested a man and woman who were also in the car.

Chicago Police News Affairs say they will brief the media on the results of the weekend operation on Monday.
