6.30pm: Jalam Ampang - A foreign teacher expressing her concern to the Kita Lawan organisers over security issues has immediately attracted media attention for a short while.
"I have some very little children in my class, like five years old. You know how they would be if they cannot see their parents as they (the parents) cannot enter the building.
"I respects their right of rally (assembly), just that I would like to express my concerns," says Anna Stevens, a Australian who teaches at British Council, a building next to the protest site.

A police source however says they will only be allowed to stay here for half an hour.
6pm: Reports fly that national laureate A Samad Said, or Pak Samad, has been arrested a while earlier. It is later confirmed to be a false alarm.

A police truck is also seen on the spot.
An angry protestor shouts at the police, but the police stand still and do not reply to the protestor.
Daylight is falling and the sky grows darker and darker and the roar of a thunderstorm is heard.
Protestors have unfurled a long banner with 'Undur Najib', 'Tangkap Najib' and 'Tangkap Rosmah' written on it.
The crowd has begun singing a modified version of 'Selamat Pengantin Baru', incorporating the lyrics 'Tangkap Najib and Rosmah'
5.40pm: Jln Ampang - A protestor holds a mirror Taoists call "the mirror that reveals the devil" with a note reading, "Rosmah, is today's RM1,200 worth?"
The mirror is traditionally used to reveal the true face of the devil who disguises in human form.
Leong Yung Hong, 21, a student tells Malaysiakini that he copied the idea from Hong Kong.
"This idea I learnt from Hong Kong. Hong Kong people use the mirror to reflect the police, while I am using this to mirror Rosmah," he says.
He explains that it was recently reported that Rosmah had allegedly spent RM1,200 for a hairdo.
Leong, clad in black, also holds a yellow umbrella symbolising the Hong Kong Umbrella revolution.
"I want to remind people of the Hong Kong people's insistence (on protesting against injustice)," he adds.

5.10 pm: Sogo - The 500-strong crowd has begun marching to KLCC.
They are singing the classic Malay wedding song ' Selamat Pengantin Baru ' (Wishing the newlyweds).
Around 20 police officers can be seen in front of Campbell Complex, and they cross the road to where the protestors are coming through.
A slight drizzle begins.
Meanwhile Klang PKR information chief Rizal Mohamad tells Malaysiakini the poor turnout is the result of insufficient planning time.
"Unlike (March 7), the information came late. There wasn't enough time to plan it properly," he says.
He adds the absence of certain leaders who have been arrested has also discouraged people from participating.
5pm: Sogo - PKR Bayan Baru MP Sim Tze Tzin says to the crowd, "This is a critical week. Next week is April fool and GST.
"We are all rising to fight against GST," he says to which someone in the crowd replies, "Greedy tax."
National laureate A Samad Said recites a poem on the spot, and the crowd turns silent and listens attentively.
The crowd starts moving to KLCC after several leaders' speeches as daylight begins to fade.
4.50pm: Sogo - Roughly 500 have gathered so far. Police presence appears to be minimail here from Malaysiakini 's observations.
While many are focusing on the speakers, somewhere in the back, a protester has brought along a toddler with them.
The little girl is sleeping in a pram, decorated with signs that say, "Help! They've stolen my future" and "No tax for pampers".
Several protesters are fanning her to keep her cool, but no one admits to being her parent.
When asked about the potential danger of bringing a toddler to the protest, they shrug it off and say, "We're just following the crowd."

Sogo - The crowd from Masjid Jamek and Dataran Merdeka have arrived, making the group 350 strong.

They have also called for the release of Anwar Ibrahim, as well as PKR vice president Rafizi Ramli and activist Hishamuddin Rais arrested yesterday.
4.20pm: Sogo - The small group of protesters has attracted the attention of many shoppers.
Shouts of "Reformasi", "Down with BN" and "End GST," fill the air.
Meanwhile a police source tells Malaysiakini only about eight people are waiting for Mat Sabu at the Dang Wangi police headquarters.
Jalan Raja Laut - The rally has taken on a festive mood, with protesters beating drums and carrying bunga manggar , which fits the group's aim to 'celebrate' Prime Minister Najib Razak's daughter Nooryana Najwa's wedding reception at KLCC today.
4.15pm: Dataran Merdeka - Two groups of protesters, one from Masjid Jamek and the other from Jalan Tunku Abdul Rahman, have arrived at a fountain next to Dataran Merdeka to join the crowd waiting there.

4pm: Masjid Jamek - Rally-goers have started marching, led by Jingga 13 coordinator Fariz Musa.
Protesters chant " Reformasi ", " Hidup rakyat " and " Bebas Anwar ".
Fariz also chants, " Tangkap Najib and Rosmah" as well as "Tolak GST".
It is unclear whether the blare of car horns heard are in support of the rally or due to the growing traffic jam.
3.55pm: PAS HQ - PAS central committee member Dzulkefly Ahmad confirms that Mat Sabu is having his statement taken at Dang Wangi.
"I have been assured that he will not be remanded, and will be released at 4 or 5pm," he says.
The 20 protesters are now quietly marching towards Sogo, led by Shah Alam MP Khalid Samad, and PAS Muslimat committee member Aiman Athirah Al Jundi.
3.40pm: Masjid Jamek - Around 50 supporters, most clad in black shirts, are seen gathering next to the Masjid Jamek LRT station.
Most are just chit chatting, and seem to await further instructions on whether to start marching or otherwise.
3.35pm: PAS HQ - It is very quiet and hot at Jalan Raja Laut, with just four Kita Lawan protesters spotted thus far.
A PAS headquarters staffer tells a dozen waiting journalists that most of those supposed to gather there have converged at the Dang Wangi district police headquarters instead.
They are reportedly waiting for PAS deputy president Mohamad Sabu to be released there before marching to Sogo.
3.30pm: Up to 5,000 Kita Lawan supporters are expected to flood downtown Kuala Lumpur today to 'celebrate' the wedding of Prime Minister Najib Abdul Razak's daughter.
The entourage will be gathering at Dataran Merdeka, Masjid Jamek, and the PAS headquarters in Jalan Raja Laut, and converge at Sogo before heading towards the Kuala Lumpur Convention Centre (KLCC) at 4pm.
The 'festivities' are part of the demand for the release of Anwar Ibrahim as well as other related issues, such as the ouster of Najib and IGP Khalid Abu Bakar and the postponement of the Goods and Services Tax (GST) slated for April 1.
The inspector-general of police (IGP) has threatened to arrest any participants in today's rally, and police have already detained at least five of the alleged movement's leaders ahead of the protest.
Among them are PAS deputy president Mohamad Sabu, PKR vice-presidents Rafizi Ramli (Pandan MP) and Tian Chua (Batu MP), Teja assemblyperson Chang Lih Kang and social activist Hishamuddin Rais - all of whom are currently being detained by the police.
With police cracking down, it remains to be seen if the day will end with protesters singing "Kita lawan sampai menang" (We'll fight till we win) or the cops chanting, "Kita tahan sampai habis" (We'll detain all of you).
