San Antonio police are asking for the public's help in identifying a woman who they said robbed a Macy's store in the 6300 block of Loop 410.

Police said the robbery occurred around 1:30 p.m. on Sept. 3.

Police said the woman was pushing a little girl in a stroller at the time.

They said a Macy's employee saw the woman take several clothing items into an elevator, but when she got off, the items were not visible.

When the employee confronted the woman outside the store, the woman threatened the employee with a small knife.

Police said the incident is being investigated as aggravated robbery with a deadly weapon.
