Two female thugs battered a Holland & Barrett shop worker who suspected them of stealing.
The employee was left with head injuries after the suspected shoplifters repeatedly punched her and smashed a door.
Shocking footage shows members of the public fighting their way into the shop in Croydon, south London, in a desperate bid to help the worker.
The dramatic video clip shows the door suddenly giving way and the alleged shoplifters making a break for it.
The video was posted to social media and captioned: "I witnessed this today in Croydon, these kids are just running wild.
“I’d be gutted if my mum came home from work saying this happened to her.”
