In a statement, RoS said it had identified three of the nine associations linked to the event held in Kajang on Dec 1.

“RoS has issued a notice for the committee members of the associations to give their statements over their involvement in the event,” it said.

It said the remaining six outfits were unregistered and warned that members could be imprisoned for breaking the law.

On Wednesday, police said they had identified the nine associations and four individuals who spoke at the event, including Sungai Pelek assemblyman Ronnie Liu.

Three others are from Persatuan Persahabatan Abad ke-21, the Communist Party of Malaya (CPM) and Persatuan Kawan Karib Sarawak.

Under the Hatyai Peace Accord between the government and CPM, members of the party were allowed to return home, on condition they did not revive their struggle here.

The accord came under the limelight in the wake of the controversy surrounding the return of former communist leader Chin Peng’s ashes to Malaysia.
