Centralia police Sgt. Carl Buster said the officers were called to a home at Roanoke Street and Ahlers Avenue after a passerby heard a woman yelling and thought there was a fight.
When the officers arrived they discovered that the reason the woman was screaming was because she was in labor.
"The woman was literally bent over trying... to keep the baby from being born," Buster said. "She told them this baby is coming right now."
The officers had the woman get on the ground and with one push the baby boy was born.
Buster said an ambulance arrived a few minutes later to take the woman and her newborn son to a hospital to be checked out.
"Mom and baby are doing just fine," he said.
The incident was definitely a change of pace for the two officers involved.
"No one ever calls the police when something good is going on. We always get called to bad stuff," Buster said. "For it to be something so cool, that's a once-in-a-career call right there."
