CHICAGO -- Police are investigating what could be the third crime in a series of robberies involving a knife-wielding suspect.
A suspect entered The Blues Jean Bar in the 2200 block of North Halsted around 2:30 p.m.
The suspect pretended to pay for an item and when the clerk opened the register, the suspect pulled a knife and demanded cash.
On May 13, there was a similar crime at women's clothing store Londo Mondo just one block from The Blues Jean Bar.
And on May 6th, police suspect the same man may have also hit the Green Goddess boutique in buck town along North Damen was the target. But this time the female clerk fought back. She got more than a dozen stitches in her hand when she grabbed the robber's knife.
While police aren't connecting all three crimes quite yet, there is an uncanny similarity in the description of the suspect and the way he operates. The African American male could be in his 20s or 30s, is 5'4-5'8 and 150-230 lbs. He leaps into action while a cash transaction is underway when the drawer to the register is open.

Anyone with an information is asked to call Area North Detectives.
