The incident was reported around 8:02 a.m. on west State Street and north Arthur Street. Dispatch said the woman, who was later identified as Crystal L. Knapek, 40, of Boise, was clogging traffic and drivers had to slam on their brakes to avoid hitting her and the baby.
Officers tried talking with her once they got on scene. BPD says they found the child was in danger, so they contacted Idaho Department of Health and Welfare.
Boise Police say the officers had to physically restrain the woman to safely take the baby away from her.
The woman was taken to the hospital for evaluation. BPD says Knapek has been charged with injury to a child, indecent exposure, resisting and obstructing, controlled substance- use or under the influence in a public place.
