BOULDER, Colo. — Officers with the Boulder Police Department are searching for a man who allegedly robbed a woman at her home Tuesday evening.

BPD said around 6:20 p.m., officers responded to the 3100 block of 11th Street. Police say an elderly woman was on her porch checking her mail when a man approached from behind and demanded her purse. When the woman refused to comply, the man pulled hard on the purse, causing the woman to roll down the steps.
