PLAINFIELD – At the very least, anyone now brought into Plainfield police headquarters after an arrest might be able to take solace in that they’re occupying brand-new jail cells. The three newly-renovated cells are now open for use after a two-week tear-down project that dissembled decades-old holding areas that police officials said were unsafe and fairly easy to break out of. “Those old cell doors were designed for use in hallways, as a way to partition off areas and not as actual cells,” Deputy Chief Will Wolfburg said. “They wouldn’t close properly, and we’ve had occasions when prisoners were able to manipulate the doors open.”
