Detroit police took a person of interest into custody Monday morning, and WWJ's Charlie Langton was there.
The arrest happened on Connecticut Street in Highland Park, where police were also executing search warrants on several houses.
A motive for the shooting is unknown, though police did say it did not appear to be random.

Officers are reviewing surveillance video from inside the restaurant.
