Illinois Gov. Pat Quinn (D) announced Wednesday he would send 40 Illinois State Police troopers to Chicago to bolster the city police department’s patrol efforts.

The troopers will be used in “surge teams” consisting of two state troopers and five Chicago police officers each that track down those wanted by law enforcement with violent crime histories in four neighborhoods, according to the governor’s office. The move comes after Chicago Mayor Rahm Emanuel (D) requested assistance from the state.

“The state of Illinois will do whatever is necessary to protect public safety – in Chicago and every community across Illinois,” Quinn said in a statement.

State troopers were last sent to Chicago in 2008 by then Gov. Rod Blagojevich (D), according to the Chicago Tribune. Fifty troopers were deployed to patrol interstates.

On Friday, the Chicago Police Department announced crime was down 14 percent and the number of murders in the first seven months of the year was at its lowest levels since 1963. Shooting incidents were up 6 percent.
