CHICAGO — (CNN) An Illinois police officer was shot and killed in Lake County on Tuesday, authorities said, and a search is on for three suspects.
Law enforcement on foot and in helicopters are combing the area, said Lake County Sheriff’s Sgt. Christopher Covelli.
The shooting happened about 10 minutes before 8 a.m., according to the sergeant. The slain officer worked for Fox Lake Police, a community of about 60,000 people in Lake County, about 60 miles north of Chicago.
The officer radioed that he was pursuing three suspects on foot, according to Cavelli.
The officer described them as two white men and one black man, he told CNN. Radio communication dropped off and backup officers were sent. They found the officer with a gunshot wound. He was a 32-year veteran of the police force, CNN learned from a law enforcement source.
Canine units have also been dispatched. U.S Marshal officials and agents with the Federal Bureau of Investigation and Bureau of Alcohol, Tobacco, Firearms and Explosives are assisting.
Residents have been asked to remain inside their homes and businesses, Ca said. Some schools have been placed on lockdown, he said.
“We asked residents to report any suspicious activity they happen to see, whether they think it’s something minor or major and to keep an eye out for these three individuals,” Covelli said.
The Federal Aviation Administration has issued a no-fly zone that covers two nautical miles over the search area.
