A Hamilton police officer went above the normal call of duty early on Friday morning, delivering a baby girl at a west Hamilton residence.

Around 3:35 a.m., police arrived at a home on Henry Street, near Main Street West and Dundurn Street South, responding to a call about a 37-year-old woman who was in labour with contractions only two minutes apart.

Two minutes after police showed up, one of the officers delivered a baby girl, with three other officers standing by, said Debbie McGreal-Dinning, a spokeperson for the Hamilton Police Service.

EMS crews arrived a short time later and took the mother and her baby to McMaster Children's Hospital.

The officer who delivered the baby has been working for the Hamilton police for three years, said McGreal-Dinning.

The baby is doing well, she said, adding the mother is also in good health, but is "very, very overwhelmed."
