Paula Staten said her daughter was forced off the pavement on Briggate by two cars used in an attempted robbery at the Rolex store on Commercial Street at midday on Sunday.
Police have now said that two cars carrying a group of balaclava-clad men attempted to ram the shop, and broken glass can be seen in photos from the scene.
They failed to gain entry to the store and escaped in the cars a few minutes later, in the direction of Hunslet Road.
Nobody was injured and police remain at the scene.
Paula posted about the incident on Facebook:
"My daughter just rang me heartbroken. She was walking down Briggate and two cars came zooming down - absolutely frightened the living daylights our of her. The car ended up in the Rolex shop window. It’s carnage on Briggate."
Anyone who saw the attempted robbery or has information or phone footage of it is asked to call Leeds District CID on 101 referencing police log number 751 of 18 February
