PKR vice-president Rafizi Ramli is the latest to fall victim to an ongoing police crackdown on freedom of speech.

The Pandan lawmaker was arrested under the Sedition Act in connection with the planned Kita Lawan rally tomorrow.

"It is understood he was arrested under the Sedition Act over a directive he circulated recently about the Kita Lawan rally," PKR said in a statement late this afternoon.

It said Rafizi, who is also PKR secretary-general, has been taken to the Dang Wangi district police headquarters.

In a statement issued yesterday, Rafizi called for the mobilisation of party members to take part in tomorrow’s Kita lawan rally.

The Kita Lawan movement was created following the jailing of Opposition Leader Anwar Ibrahim last month.

Since then, more than a dozen activists have been arrested over the series of protests organised by Kita Lawan.

Protesters tomorrow will gather at three locations - Masjid Jamek, Dataran Merdeka and the PAS headquarters from 4pm, before marching to the Sogo shopping mall and on to the Kuala Lumpur Convention Centre (KLCC).

Najib's daughter, Nooryana Najwa Najib, who is married to Kazakhstan national Daniyar Kessikbayev, will be holding a wedding reception at KLCC tomorrow night.

DAP has refused to mobilise its members to take part in the protest on grounds that it does not want its members to gatecrash the wedding party.
