Three World War II-era grenades were recovered from a Wrigleyville residence Wednesday, officials said.
Reports of the explosive devices prompted the evacuation of three multi-unit buildings in the 900 block of West Newport Avenue and a response from the Chicago Police Department's Bomb and Arson Unit shortly before 3 p.m.
Neighbors told NBC Chicago they heard old hand grenades were found in a basement.
"I was just cleaning my house and I walk out back and saw a couple of cops riding their bikes around. I'm like, 'Is everything OK," and they're like, "It might be,'" said one neighbor. "It's always something exciting in this neighborhood, I tell you."
The neighborhood where the grenades were found is about two blocks away from Wrigley Field, where the Cubs played the San Diego Padres at 1:20 p.m.
Bomb unit officers called the fire department to handle the grenades as hazardous materials.
The devices will be destroyed in a safe location, police spokesman Darryl Baety told the Chicago Tribune.
