The company contracts with a private security firm to patrol the parking lots and says after these incidents, mobile patrols will be increased at all of their lots. The company operates more than 30 parking locations in downtown Milwaukee.
The company says it's also upgrading camera systems and installing new systems where needed.
"This is our hometown so to have this happen in our backyard is extremely disturbing to us," said Executive Vice President of Operations Ethan Spiegelberg in a statement Monday. "We're going to do whatever it takes to get this stopped."
For people parking in the lot on Monday, there was still a lot of concern.
"Kind of makes me a little worried to park here for sure," said Mike Adams.
The Wisconsin Department of Transportation operates the Intermodal Station building. A spokesperson said Monday in a statement:
"WisDOT has been in communication with Colliers International who will be coordinating with Interstate Parking to add additional lot surveillance. In addition, signs will be installed notifying people that the lot is under video surveillance. Any affected individuals may contact Interstate Parking at 414-431-6555 for reimbursement for their parking."
Interstate Parking includes fine print on parking ticket vouchers that says the company is not responsible for loss or damage to vehicles or contents.
