Police say an intruder attacked a blind woman inside her home before her guide dog alerted police.

Investigators say the 54-year-old woman is hospitalized in stable condition following the early morning attack Monday in the city's Wynnefield Heights neighborhood.

Authorities say the intruder came in through an open door, choked the woman and threw her down a flight of stairs. Investigators say the woman's seeing-eye dog then used a special device to contact police.

The woman's attacker fled the scene.
