Video: Bus driver rescues young child

A Milwaukee bus driver rescued a young child who was wandering barefoot on a freeway overpass in frigid temperatures, authorities say.

The Milwaukee County Transit System says the girl was less than a year old and wearing only a diaper and a onesie when bus driver Irena Ivic spotted him on Dec. 22. Security video shows the girl toddling down the overpass.

The video later shows Ivic stopping her bus, running across the street, picking up the crying child and carrying her to the bus.

As Ivic called for help, a passenger gave up her coat to keep the girl warm before police and firefighters arrived. Authorities say the child was cold and frightened, but otherwise OK.

Police say the child had been left outside by his mother who may have been suffering from a mental health crisis.

NOTE: Police first said the baby was a boy but later clarified that the child is actually a girl.
