The red-shirts have occupied Masjid Negara, one of the gathering points for tomorrow's Bersih 5 rally.

However, Sungai Besar Umno chief Jamal Md Yunos, who leads the red-shirts, is nowhere to be seen.

Instead, it was Jamal's lieutenant Razali Zakaria who took charge at Masjid Negara.

"We will be here until tomorrow. More will come here in batches and continue to gather here until tomorrow,” Razali told reporters.

Jamal was supposed to be present at Masjid Negara to announce that the red-shirts would be occupying the area starting today.

Razali said he and the other red-shirts leaders did not know Jamal's whereabouts.

Another individual close to Jamal also said he didn't know of his whereabouts as speculation intensified that Jamal too had been arrested.

However, this could not be confirmed with the police.

"I don't know, as I wasn't able to contact him. None of us know where he is. When I last contacted him he said he was on the way (to the national mosque).

"But now, when I call him, he is not available. We don't know where he is," a close aide of Jamal told Malaysiakini on condition of anonymity.

Other red-shirts leaders, however, said Jamal may be keeping a low profile amid mass arrests by the police ahead of the Bersih 5 and red-shirts rallies tomorrow.

Malaysiakini's repeated attempts to contact Jamal have been unsuccessful.

Later in the evening, police arrested Razali.

Following Razali's arrest, most of the red-shirts left Masjid Negara, leaving only a handful of activists behind.

The 10-odd red-shirts were there for logistics and were carrying food into the mosque.

In a statement later in the night, an elusive Jamal lauded the arrest of Bersih leaders.

At least 11 people have been arrested before the Bersih 5 and red-shirts protests tomorrow.
