They were arrested when they gave themselves up at the Kluang police headquarters at 1.40pm, Berita Harian Online reported.
Kluang district police chief ACP Mohamad Laham said the detention was to facilitate investigations into the case where Pakatan Harapan members were stopped and chased away from distributing dates to the public at the bazaar yesterday.
One of the suspects is said to have punched one person distributing dates and another for pushing others.
“We have identified four others and they will be held soon to help in investigations,” Mohamad told the news portal.
The investigations are being conducted under Section 324 of the Penal Code for causing hurt and Section 506 for criminal intimidation.
A video showing the group confronting Kluang DAP MP Liew Chin Tong and his Pakatan Harapan entourage became viral.
He is said to have faced a similar situation at the bazaar three years ago.
Several police reports were lodged over the incident.
Umno Youth chief Khairy Jamaluddin, who is youth and sports minister, criticised the actions of the group.
“Such action is not right, especially during the fasting month. We don’t have to behave like this although we have different political beliefs,” he said through Twitter this morning.
PPBM president Muhyiddin Yassin also criticised the incident, saying it was unIslamic and Liew should not have been abused with vulgarities as he had the right to meet his constituents.
