The Home Ministry is colour blind in upholding the law, says Datuk Seri Dr Ahmad Zahid Hamidi.
"The Minister through the police has conducted a thorough investigation on the ruckus at Low Yat Plaza.
"The police will take necessary action on any guilty party regardless of race," he said in a statement on Tuesday.
He added that those responsible for stealing, rioting and spreading false news online to incite racial tension would not be let off the hook.
"We will ensure that justice is delivered in this matter.
"The guilty party will not escape the police's reach," he said.
According to the Low Yat Plaza management, a suspect was apprehended at 5.40pm Saturday for allegedly trying to steal a mobile phone from one of the kiosks at the shopping complex.
It said that after this happened; a group of youths turned up at the mall and damaged another outlet in retaliation, claiming that the outlet's staff had assisted in apprehending the suspect.
On Sunday, several people, including three journalists, were injured in a mob attack after police dispersed protesters at the mall.
An eyewitness said a group of men barged into a food outlet near the shopping mall around midnight and assaulted patrons with motorcycle helmets.
So far, 19 people have been detained over the incident.
