Three of the seven KeADILan leaders sought by police have been nabbed by police by about 6pm today, with the first detainee, party's information chief Ruslan Kassim, picked up at 3am and ordered by a magistrate to be remanded for seven days for further investigations.

Police has also called on another four KeADILan members to present themselves at the nearest police station for their involvement in organising the "Black 14" people's gathering at the National Mosque tomorrow.

They are KeADILan vice-president Chua Tian Chang, Subang Youth chief Lokman Noor Adam, Bukit Bintang division chief Sanusi Abdullah and Youth executive secretary Muhammad Zahid Md Arip.

"We want them to contact the police immediately failing which we will arrest them before tomorrow's planned illegal gathering," Director of Internal Security and Public Order Abdul Hamid Mustapha told reporters at Bukit Aman police headquarters today.

KeADILan youth chief Mohamed Ezam Mohd Nor was arrested at about 3pm today in Sungei Petani, Kedah after performing Fridays prayers at Masjid Pengkalan Sim, according to the opposition party sources.

Early this morning at about 3am, the first of seven KeADILan information chief Ruslan Kassim was arrested at his house in Selayang.

By about 5pm, malaysiakini has confirmed that a third KeADILan leader, executive committee member N. Gopalan Krishnan, had been arrested at a roadblock in Rantau Panjang, Kelantan, where he was due to lead a contingent of supporters to Kuala Lumpur by train.

The arrests of the three KeADILan leaders happened even as national news agency Bernama reports today from Havana quoting Prime Minister Mahathir Mohamad as saying that the "government is not trigger-happy in acting against those behind the planned demonstration".

"If we are trigger-happy, by this time, most of them will be under detention," he was quoted as telling a news conference when asked if the government would invoke the Internal Security Act against the demonstrators.

Mahathir, who is in Cuba attending the South Summit of the Group of 77, in reply to a foreign journalist's question if the government was adopting scare-tactics against intending demonstrators, said it was up to the opposition to have such a perception.

"Demonstration and violence is not something that the Malaysians would welcome," he added, emphasising that the government had a duty to ensure the people's safety.
