Police officers and FBI agents raided the home of a suspect near Grayslake Tuesday morning in an ongoing sexual assault investigation involving a child, officials said.

The Lake County Sheriff’s Office, Grayslake Police Department and the Federal Bureau of Investigation (FBI) conducted a search warrant in the 33100 block of North Sears Boulevard in Wildwood, which is unincorporated Grayslake.

The raid occurred around 6 a.m. Tuesday in regards to an ongoing sexual offense investigation that involved a child victim, according to Lake County Sheriff Spokesman Lt. Christopher Covelli.

Covelli said the FBI was assisting in the investigation as it was believed the offender took the child out of the country at one point.

The male suspect is in police custody and the child is safe with her mother, Covelli told Lake and McHenry County Scanner.

The suspect was previously arrested on a warrant a week ago and the investigation into his crimes is ongoing.

Police believe he sexually assaulted the child on numerous occasions in Lake County, including in Waukegan, Libertyville and Grayslake.

The Lake County Sheriff’s Office’s child advocacy detective worked with Waukegan, Libertyville and Grayslake police departments in the case to develop information in coordination with the victim.

Charges against the suspect are pending and more information is expected to be released once they are filed, Covelli said.
