Portland police are continuing to investigate an armed robbery at a Sagamore Village apartment Friday.
 Police said Sunday they had yet to arrest anyone in connection with an early morning incident at the home of a 40-year-old woman who told police three masked men had broken into her apartment on Josslyn Street. Police said the men fired a gunshot, tied up the woman and her children, ages 9 and 11, and fled with cash and a briefcase.
