On Thursday, police questioned three teenagers about those and other recent incidents.
Warren police Chief Timothy Bowers confirmed the city has four open investigations involving reports of vandalism and criminal damaging at the city-owned parking deck. However, he said that as of Friday no one had been charged.
He said investigators are reviewing surveillance recordings that show three individuals on bicycles in the parking deck. At one point two individuals appear to be passing a knife back and forth.
