It was a petty issue blown out of proportion, say retailers and salespersons who witnessed Sunday's melee following the theft of a smartphone at Low Yat Plaza.
A man, who only identified himself as Wan, said the ruckus was not racially motivated.
"If the guy stole, it is wrong, by all means arrest him. I don't look at whether he is Malay or Chinese. A crime is a crime.
"This is a petty issue which has been blown out of proportion," he said.
An employee of a telecommunications company, who only identified himself as Fazlan, was concerned for the safety of his Chinese friends.
"I have been working here for the past 10 years and things have been okay among us."
A telecommunications company branch manager, Mustaza Halim, said they had taken necessary measures to ensure that the security of their staff was not compromised.
A retailer, who only wished to be identified as Wang, feared for his safety and that of his workers, and that his stock might be stolen.
"I don't believe there are many racists in Malaysia but I do believe there are a lot of opportunists who would take advantage of this incident.
"I'm worried some of them would come here on the pretext of fighting against injustice when they have a different agenda - which is to steal and create a ruckus.
"When there are too many people acting aggressively, how can we stop them from thrashing and stealing things?" he asked.
A 25-year-old sales personnel, who refused to be identified, said she was afraid that retailers, as well as workers, would be attacked by thugs although they were not involved in the misunderstanding.
"We closed our shop as early as 7.30pm on Sunday after the thugs began swarming the mall. Some of them just blindly attacked whoever was in their way.
"Although we are working as usual today (Monday), we have been instructed by our bosses not to wear our official attire."
On Saturday, a fight erupted between thugs and sales assistants after a group of youths came to the shop at Low Yat Plaza to seek revenge against the retailers who allegedly caught a shoplifter.
