Five cars stolen in all, leaving a trail of glass shards on the street in the crime wave's wake.
The Corktown Business Association is concerned about customers and worked trying to reassure them that they're working on the problem.
"One, people know that we have safe, secure parking in Corktown and a lot of it," said Dave Steinke of the Corktown Business Association. "Two, that if there is a problem that there is going to be a new detail in downtown Detroit. And there's going to a detail in Corktown from the DPD."
Restaurant owners say they have spent a lot of money to provide secure parking for customers and they are glad to be getting help from the city.
"We do have resources deployed to the Corktown area to the patrons."
Detroit Police Chief James Craig announced a new mobile reporting unit that will be visible and able to take reports of auto theft and break-ins.
Corktown wasn't the only place with problems over the weekend - six cars parked on the rooftop at Cobo Sunday night for a Joe Louis Arena concert were broken into.
"We are looking, as a reminder, to make sure that people aren't leaving valuables in plain view," Craig said. "I don't care what city you are in, in America. If you have an iPad, cell phone, cell phone cords, they have to be tucked in where they won't be from visible from the street."
