1.30pm: Bersih chairperson Maria Chin Abdullah has condemned the distribution of contaminated drinks to rally goers that allegedly resulted in the food poisoning incident last night as an "insidious act" made in the guise of supporting the rally.
"These drinks have caused participants to have stomach pains, vomiting and diarrhea.
"This seems to be an act of sabotage and an attempt to poison our participants, who have since been given medical attention and taken to the hospital," she says in a statement today.
"We urge the police to investigate this as soon as possible and bring the culprits to justice. Police reports have been made," she adds.
According to a videoclip by the Bersih medical team coordinator Tan Gengta accompanying the statement, what appears to be new packets of soft drinks are shown to contain minute puncture holes.
Contaminants had allegedly been injected into the drinks through these punctures, claims the video.
Maria warns participants to be vigilant and refuse any free drinks distributed by those not authorised by the Bersih 4 organising committee.
"If they do, we advise them to check the top seam of the packet drinks for puncture holes, and if found, immediately report it to the security unit," she says.

1k march 'Najib' to Parliament
12.45pm: Jalan Tun Perak-Jalan Raja intersection - With renewed vigour after their lunch, a group of around 1,000 protesters march from Jalan Tun Perak towards Jalan Parlimen before turning around at the intersection here to head back the way they came.
At the head of the small parade, someone is carrying a mid-sized papier maché chicken on a stick, to symbolise Najib as his name is similar to the word 'chicken' in Mandarin.
The crowd cheers at the sight of the chicken and some join in to follow it.
Despite the Bersih organisers telling the protesters to stop using the vuvuzelas as they are very disrupting, many people are still trumpeting away as the parade marches on.
