The Forsyth County Sheriff's Office said the man was wearing gloves and carrying the air filter and a toolbox when he entered the Best Bank in the Kroger supermarket in Cumming shortly after 10 a.m. Monday, The Atlanta Journal-Constitution reported Tuesday.
"He used the air filter to try to conceal his identity from the employees. I guess he didn't see the camera," Deputy Matt Runion said. "He did not produce or threaten to use a weapon during the robbery."
Investigators said they are working to identify the man, who got away with an unspecified amount of cash.
