The 7 Investigators have learned an office at Flint City Hall was broken into and ransacked sometime before or after Christmas.
A window was smashed, allowing the burglar into an office filled with public works documents.
“When we came in and with the window being broken like that, and papers being thrown all over the floor, it was a mess,” said Flint Mayor Karen Weaver.
There are security cameras at city hall, but they were not working in the area of the break-in.
The city says they don’t know exactly what documents were there to begin with, so they can’t say what may have been taken.
But from the outside, the office appears to have papers, and one that says ‘Public Works’.
"I don't know what was in all those file cabinets. I don't know what was all in those standing files," says Weaver.
Police Chief James Tolbert added, "That's going to be our first hurdle, to try to address were any documents taken [related to the water crisis].”
In the meantime, officers are stepping up patrols around the complex.
The chief told 7 Action News Thursday, there are no leads or suspects.
