PETALING JAYA: Four handphone salesmen have been arrested by police in connection to the riot that broke out at Low Yat Plaza Sunday, with 30 others brought in to assist investigations.

KL CID chief Senior Asst Comm Datuk Zainuddin Ahmad said the 30 were brought in to identify some of the assailants in the riot Sunday night

"Four other retailers were arrested to facilitate investigations into a riot incident," he said.

SAC Zainuddin added there have been a total of 22 people arrested by city police, while Bukit Aman CID arrested Mohd Ali Baharom, also known as Ali Tinju, earlier on Tuesday.

The arrival of the police to pick up the 30 people caused a minor panic at the mall.

According to witnesses, police started picking up workers from various stores, forcing some to close as there were no workers there to man them.

Curious shoppers started to gather at the concourse area and as a huge crowd gathered, panicked traders on the upper floors also closed their shops.

The crowd dispersed peacefully after being told by mall security personnel some 30 minutes later.

Those picked up by police were later released and returned to the mall.
