A 7-11 store was robbed on the Northwest Side, and the store owner traded gunshots with a couple of the suspects involved.
It happened at about 1:30 a.m. Friday in the 2900 block of West Montrose.
Police say there were four robbers in all, though only two of them went inside.
A witness says the shootout took place in the alley behind the store.
A clerk says he gave the robbers more than $100 in cash before they drove off in a dark-colored sedan.
No one was injured.
Sources say the owner has a concealed-carry permit.
