A fight broke out in the ladies wear section of a busy Walmart in Hesperia this Sunday.
The fight started between two women but male bystanders soon became involved. One man was knocked out cold and taken to the hospital.
The man responsible for the knockout punch left the store after the fight but then returned. Customers and employees were scared that someone was going to pull out a gun.
A 24-year-old man from Adelanto was arrested on suspicion of battery, the deputy said.
