Washington  - A Canadian woman who gave birth to twins on a freezing street in Windsor, Ontario amidst snow and rain was in good condition and the newborns were expected to survive, it was reported Thursday.

Police officers on a routine patrol first thought they were at a crime scene when they saw a woman covered in blood screaming for help and waving them down. The
27-year-old woman was clutching a baby and said she had just given birth, the Windsor Star reported.

While ambulances were still still on their way, the woman delivered a second baby before midnight Tuesday.

Staff at the Windsor Regional Hospital said Thursday that the mother and babies were doing well. One of the newborns was said to be in serious condition Wednesday. The premature babies weighed in at 1.8 and 1.3 kilograms.

"Our officers deal regularly with tragic circumstances. This was extremely unusual ... traumatic," Windsor's deputy police chief Jerome Brannagan was quoted as saying.

The Children's Aid Society (CAS) was investigating the circumstances that led to the woman giving birth on the street.

"We are looking into it to ensure the safety of the kids and make sure the mother is okay ... and that the mother is in a condition to look after the children," the society's executive director Bill Bevan said. (dpa)
