The match was postponed because of adverse weather.

Ipoh police chief Abang Zainal Abidin Abang Ahmad said seven of the suspects, aged between 19 and 32, were detained for their involvement in the disturbances and provocation.

The case is being investigated under Section 160 of the Penal Code for rioting, he said in a statement today.

He said a 16-year-old youth was also arrested for throwing a bottle at a police officer on duty, with the case being investigated under Section 186 of the Penal Code for obstructing a public servant.

All eight tested negative for drugs and had no criminal records.

“Police are finalising their investigations and will refer the papers to the Perak public prosecutor’s office for further action,” he said.

The Malaysian Football League said the match will be rescheduled to a later date.
