Violence broke out at a forum attended by former Malaysian prime minister Mahathir Mohamed on Sunday, a member of Mahathir's party said.
The town hall meeting was aimed at highlighting a major financial scandal that has ensnared Prime Minister Najib Razak, and which has spurred Mahathir, 92, into coming out of retirement to take on his ex-protege.
Moments after the brawl started, security personnel quickly escorted the former prime minister, his wife Tun Dr Siti Hasmah and other national Pakatan Harapan leaders to the rear exit of the Raja Muda Musa Hall. A Parti Pribumi Bersatu Malaysia (PPBM) leader said today the party proceeded to hold the "Nothing to Hide 2.0" forum, despite being tipped off about potential trouble as its chairman Tun Dr Mahathir Mohamad was not afraid to confront his critics.
"We realised this when we saw hundreds of youths that are not members of Armada but had Armada tees on... we feared something would happen", he added.
Syed Saddiq expressed disappointment at the incident which took place around 5.30pm, as Dr Mahathir was answering a question from the audience on the Memali tragedy in 1985.
"They (protesters) only used knives and sharpened bamboos Tun?"
Dr Mahathir, responding calmly, said, "Four policemen were killed. What the police did was proportionate with the threat, it was their SOP".
The commotion inside the hall also saw another flare tossed towards a section where media members were seated.
Meanwhile, Shafien said three suspects, aged 17, 18 and 19 have been detained following the incident.
There were reports that the suspects were assaulted by the PPBM mob before they were handed over to the police. Forum organizer Syed Saddiq Syed Abdul Rahman said several people were injured but couldn't give details on the exact number or their condition.
At least two flares were also released at the venue.
