Police are looking for a man who stole a safe and electronic equipment from the office of a Danvers nursing home over the weekend. The man entered two Danvers nursing homes, but one had no equipment reported stolen, said a police spokesman, Sergeant Robert Bettencourt. Police suspect that the man is targeting the offices of the homes. “We do not believe he’s entered any rooms,” Bettencourt said. Bettencourt said the man also stole from a nursing home in Waltham, and police believe he has stolen in other locations. Police are not releasing the nursing homes’ locations because investigations are ongoing, Bettencourt said.
