Three policemen were injured as a result of the aggressive situation and police also discovered four parangs and three knives in a drain at the Dayabumi Complex, situated not far from the location of the rally.
Police named four NGOs as organisers of the event, namely Gerakan Turun Kos Sara Hidup (TURUN), Solidariti Mahasiswa Malaysia (SMM), Jingga 13 and Solidariti Anak Muda Malaysia (SAMM).
On Dec 24, police detained TURUN chairman Mohd Azan Safar, 24, under Section 9(5) of the Peaceful Assembly Act 2012 and Section 124 (B) of the Penal Code.
Salleh said police will take action on the organisers because they had received 1,936 police reports from NGOs and individuals who protested against the event.
"This shows that a majority of 28 million Malaysians were against the rally because they are confident with the country's democratic system.
"The people know there are other ways to channel their woes, which includes getting representatives to raise their problems in Parliament and that rallies are not a solution," he said.
Salleh also praised the police for being professional in controlling the situation last night. - Bernama
