Melaka police chief Mat Kasim Karim said the individuals must go promptly to the Melaka Tengah district police headquarters in Bandar Hilir here to help in investigations under Section 148 of the Penal Code, namely for rioting using weapons.

‘’I hope all those involved in the riot yesterday will step forward to help in the police investigation.

“I also want to advise all participants in the convention to be more disciplined and professional,’’ he said through a statement here today.

Yesterday, the congress, which was attended by 1,000 delegates at the Melaka International Trade Centre, was marred by a commotion, triggering a quarrel between supporters and injuring two individuals.

Kasim said further investigations on two men who were detained to help in investigations over the case yesterday found that one of the suspects had a drug record. Both were remanded for two days for further investigation.

He said preliminary investigation of the case found that two groups were involved in the incident, one wearing blue shirts and the other black shirts.

‘’The first incident took place yesterday at 8.25am and the next one at 12.30pm,’’ he added.
