The 25-year-old man was arrested after police released a sketch earlier this week in connection to a string of robberies. Police believe four strong arm robberies in Lincoln Park are related.
However, four other recent attacks in Lakeview and Ravenswood are not believed to be connected.
Officials said a tip led them to the man, who was ID'd by a victim in the August 1 attack in the 2000-block of North Cleveland.
"I am encouraged that we have someone who is of interest and he's speaking with us," said Superintendent Jody Weis, Chicago Police Department

Just last week, statistic show that there was an uptick in robberies in Lincoln Park- but that crime in Chicago is down overall.
