KUALA LUMPUR: DAP's Teresa Kok is the latest to be arrested under Section 73 (1) of the ISA Friday

Kok, who is Seputeh MP and also assemblyman for Kinrara, was arrested at 11.20pm Friday over a religious matter concerning a mosque.

Deputy IGP Tan Sri Ismail Omar confirmed Kok's arrest.

Kok was arrested while on the way to her home in OG Heights in Old Klang Road here after a function in Bandar Utama.

She was taken to the Wangsa Maju police station where she is being held under tight security.

Earlier, Sin Chew Daily News reporter Tan Hoon Cheng was arrested at her home in Taman Permai in Bukit Mertajam at 8.40pm Friday.

Family members said they were told that she would be taken to the Bandar Perda police station in Seberang Jaya.

Ismail said Tan was also arrested under Section 73 (1) of the ISA.

A colleague said Tan called the office to inform them that the police had picked her up at her home at 8.30pm.

However, when several colleagues tried to call her back on her handphone some 10 minutes later, the phone had been switched off.

On Friday night more than 100 people, including politicians, members of non-governmental organisations and journalists, gathered at the Penang police contingent to stage a silent protest against Tan's arrest.

Tan, who is Mass Communications graduate from Universiti Sains Malaysia, has been a journalist for nine years.

She had reported on former Bukit Bendera division Umno chief Datuk Ahmad Ismail's alleged racist remarks while campaigning for the Permatang Pauh by-election.

The arrest comes on the same day that Malaysia Today editor Raja Petra Kamaruddin was detained, also under the ISA.
