Police are trying to get to the bottom of two weekend armed robberies near Savannah’s Forsyth Park. Just before 9:45 p.m. on Saturday, three males were sitting on a bench in the park when they asked a victim for the time. As the male and female victims passed by, the suspects followed them, brandished a firearm and demanded money, said Sonny Cohrs, Savannah-Chatham police spokesman.
