In each incident, the offender was described as a Hispanic or Middle Eastern male wearing a vest similar to an Amazon delivery driver's vest, Chicago police said.
On Monday, Apr. 11, a Middle Eastern male subject entered a building in the 2000 block of North Humboldt Boulevard in Palmer Square and knocked on the door of a 36-year-old woman.
After a brief conversation, the male pepper-sprayed the woman in an attempt to gain entry to her apartment, but was unsuccessful and fled the building, police said.
In the second incident, a Hispanic male sexually assaulted a 39-year-old woman on Fri., May 5 in the 1600 block of North Humboldt Boulevard in Logan Square.
Police said the suspect followed the woman as she entered her apartment building around 3:30 p.m. The male suspect grabbed the woman from behind and slammed her head against a wall before sexually assaulting her.
On Saturday, May 7, police said a 36-year-old woman was attacked around 3:30 a.m. in the 2000 block of North Humboldt Boulevard.
A Middle Eastern male wearing a vest approached the woman as she entered her apartment building, grabbed her and placed a black bag over her head, according to police.
The woman fought off the suspect by lowering her body and screaming, causing the male to flee eastbound down the north alley of Armitage Avenue from Humboldt Boulevard towards Richmond Street.
Women who live nearby said Monday morning they were on alert.
"It's really scary," said Gwen Santana. "I mean we see Amazon people all the time. I have multiple friends who are single women who live around here and there have already been multiple attacks with gunman in this area, it just makes me feel pretty unsafe to walk around at night alone for sure,"
A pair of older women said they called their children called to warn them about the threat in the neighborhood.
Rosita Gonzalez said her daughter contacted her last night.
"Oh she's so worried. I've been living here for 29 years and ... with the crime in Chicago, it's terrible. We all have to be alert, you know? And I advise there be more cameras," Gonzalez said.
"Last night my son called me and said don't go [anymore] in the nighttime to the church, mom," said Migdalia Rodriguez. "That's why I feel very insecure."
Police described the suspect in each of the incidents as a Hispanic or Middle Eastern male, standing between 5-foot-6 and 5-foot-10 and weighing about 170 pounds. He was wearing dark clothing, a vest similar to a construction vest or Amazon vest, and a surgical mask.
