PKR lawmakers Tian Chua and R Sivarasa were called in by police today for questioning under the Peaceful Assembly Act 2012 for their alleged involvement in Himpunan 365 outside the Sungai Buloh Prison on Feb 9.

Himpunan 365 was organised in conjunction with the one-year anniversary of PKR de facto leader Anwar Ibrahim's imprisonment for the Sodomy II conviction.

After giving his statement, Chua, the Batu MP, said the police are investigating 25 individuals who took part in the rally, including him and Subang MP Sivarasa.

"We are probably the first batch (hauled up by the police)," he said.

Chua said they are being investigated under Section 9 of the Act for failing to give the police the 10-day notice before the gathering.

Chua said he was also being investigated for taking part in a solidarity gathering outside Sungai Buloh Prison on Dec 6, 2015.

For their questioning today, he and Sivarasa were accompanied by lawyer Latheefa Koya, while Selangor Menteri Besar Azmin Ali showed up to give moral support.

The Feb 9 gathering was part of PKR's effort to pressure the government to free Anwar (photo), who is serving a five-year jail sentence.

In February, Selangor government mouthpiece Selangorkini came under police investigation for its report titled ‘Lebih 3,000 gegar Himpunan 365 bebas Anwar’ (More than 3,000 attend Himpunan 365 to free Anwar).

Later, Azmin also came under police investigation for the 'free Anwar' billboards, which angered Umno.

"The government should not treat the Free Anwar Campaign as some sort of deviant and seditious activity," Azmin said.

"It is perfectly legitimate for citizens to express their views and solidarity with Anwar, who we consider a political prisoner.

"We urge the government to stop these repressive activities and wasting public resources and manpower of the police force," Azmin said, adding that the police should concentrate on combating real crimes.

Chua described the police action as a witch-hunt against activists and politicians.

Sivarasa said: "The police force and the inspector-general of police must learn to distinguish our political rights - to assemble and to criticise the government - from real crimes such as robberies and break-ins.

"This is an abuse of power."
