The Androscoggin County Sheriff’s Department is searching for three masked men they say were involved in a home invasion in Poland. Authorities say three men forced their way into a home at about 11:30 a.m. Thursday, tied up and assaulted the male resident, then made off with some cash. No weapons were used or displayed. The victim was not seriously hurt. The suspects were described as black men wearing dark clothing, gloves, ski masks and carrying backpacks. The suspects left on foot and were last seen on foot on Route 122 in Poland. A search with the help of dogs did not locate the suspects, although some evidence the suspects dropped was recovered. Investigators do not believe this was a random act.
