The Savannah-Chatham police department’s Robbery Unit is investigating an attempted armed robbery that occurred about 9:30 p.m. Tuesday near Tibet Avenue and Jameson Road. The victim, a 22-year-old male, was walking toward his residence from a nearby business with his young son who was in a stroller, said Sonny Cohrs, police spokesman. Two suspects reportedly pulled up in a vehicle, held him at gunpoint and demanded money before firing a shot at the victim.
