Chicago police are seeking the public's help in finding a man who reportedly sexually assaulted a woman early Wednesday near the CTA Red Line's Morse station.

Police have released photos of an individual they are referring to as a "person of interest" in the attack, which took place just before 6 a.m. Wednesday in the 1300 block of West Lunt Avenue, NBC Chicago reports.

(Ald. Joe Moore has shared the CTA bulletin containing eight additional photos of the man on his ward's website.)

According to ABC Chicago, a man approached the 50-year-old woman from behind when she arrived at the entrance to the Morse Red Line station, dragged her to a construction area underneath the station and assaulted her.

When the woman screamed, the man reportedly threatened to "snap her neck" if she did so again, police told the Chicago Tribune. Another woman discovered the victim while walking her dog shortly after the attacker fled the scene with her purse and other belongings, according to Fox Chicago.

The Guardian Angels on Thursday morning were at the station handing out fliers with information about the person of interest, who is a 6 foot tall black male weighing about 200 pounds, DNAinfo Chicago reports. The Guardian Angels said they will continue to patrol the area throughout the day Thursday.

Police are asking anyone with information about the crime to call 312-744-8200.
