MPD spokesman Dean Harper said a white male knocked on a door on Bragg Avenue, asking for gas money, while a second white male waited outside.
As the woman attempted to help him, the suspect entered the house, assaulted the victim and stole her purse.
"Both suspects are described as white males, both of them 5'6". One of them a skinny build and bushy black hair. The other one blonde-red hair, straight, with a heavy build," Harper said.
One person was taken into custody for questioning, but no charges have been filed.
Harper urged residents to not open their doors to strangers, and he said if you're suspicious, call police.
If you have information on these suspects, call Crimestoppers at 485-1860.
