A Methuen Police Department K-9 Unit helped officers locate and arrest a man hiding inside a commercial building he had broken into early Wednesday morning. Chief Scott J. McNamara said officers were dispatched after receiving a business alarm at 1:48 a.m., at 145 Milk St., and discovered audible alarms sounding but no open doors, windows or signs of a break-in. The company’s business manager also walked through with officers, discovering drawers and cabinets inside the building that appeared to be pried open and two televisions missing. Officer Christine Nicolosi and her K-9 partner Kilo began searching the building with Kilo leading officers to the second floor and then the third floor, where the K-9 tracked toward a dark, unfinished room containing several large cabinets that were on the floor and covered in ceiling tiles. Police discovered 42-year-old Juan Rivera of Saugus hiding there.
