Responding to a surge in house breaks this winter, Police Chief Michael J. Bradley Jr. has issued a warning to town residents to make their homes more secure. A Grafton man was arrested in connection with several break-ins in area communities, including Upton, where there were six break-ins in a two-week span, Bradley said. The Police Department’s page on the town website, www.uptonma.gov, offers several tips on how to reduce the chances of a break-in, with the list including to create the appearance that someone is home during the prime break-in hours of 10 a.m. to 2 p.m., lock all doors and windows, and hide valuables in areas other than the master bedroom. Bradley also advises homeowners to invest in heavy-duty deadbolts and solid-core or metal doors, especially for entrances that are hidden from a street view. Most importantly, he said, if someone attempts to break in while you are home, or if you come home and see something wrong, do not confront the thief. Call 911 and follow the directions of the dispatcher, the chief said.
