Officers are on the scene in the Cobb County neighborhood, about 20 miles north of downtown Atlanta.
“Barricaded Gunman/Shelter In Place,” a Cobb County Police tweet said. “All neighbors on Kingsley Dr between Castle Lane and Vineyard Court need to shelter in their homes.”
No further details were immediately available.
The home is in a residential area in an upper middle class neighborhood.
This is a developing story. More to come.
