The woman does not know her attacker.
Tonight's victim was not robbed.
Two weeks ago, however, the Chicago Police Department issued a community alert to warn residents of a robbery pattern in which victims were threatened with or struck with a hammer. One of the incidents listed in the alert was carried out by a lone male, black in the 2800 block of N. Southport, about three-quarters of a mile from tonight's incident.
