FORT WAYNE, Ind. (WOWO): Police are investigating an armed robbery and home invasion on Suttenfield Avenue. A woman told officers a black man who she thought was her son's friend knocked at her door Tuesday around 6 PM. He pushed his way in, then let 3 other men wearing ski masks inside. One suspect hit the woman in the head with a gun and demanded money. The woman gave the men cash, but they wanted more and searched the home before finding one of the woman's daughters, who they thought had called police. The suspects ran from the home, and police believe they had a car waiting for them.
