Knife-wielding suspect linked to 3 Chicago robberies

CHICAGO (WLS) -- A man wielding a knife during boutique robberies in Lincoln Park and Bucktown is now linked to a robbery in the Austin neighborhood.

Police said the armed robber targeted a Dunkin' Donuts in the 5700-block of W. North Avenue on Monday.

Last week, the Londo Mondo store on Halsted in Lincoln Park was hit. The suspect pulled a knife and demanded money from a store clerk, but no one was hurt.

The robbery also closely matches one at The Green Goddess Boutique in Bucktown a week earlier, where a clerk was slashed during a struggle with the robber.
