A toddler spent several hours trapped in bank vault in suburban Atlanta, MyFoxAtlanta reported Friday.

The ordeal ended when an emergency locksmith was called in to open vault and free the 2-year-old.

The girl was at a Wells Fargo bank branch in Conyers around closing time with her mother and grandmother, who worked at the bank.

Investigators said the child wandered into the bank vault, which shut behind her, and was spotted on security cameras.

Police and firefighters arrived at the scene, but were unable to open the vault because it was on a timer and had locked for the night.

Conyers Police Chief Gene Wilson told reporters it was a "very tense scene" as authorities stood by along with the relatives, and rescue workers pumped fresh air into vents leading to the vault.

Authorities said the baby could be heard crying during the rescue.

The toddler was finally reunited with her mother after four hours.

"That was one of the better moments I've ever witnessed," Wilson said, adding the girl was fine save a needed diaper change.
