Police fired tear gas at about 11pm today to disperse 500 residents who had tried to dismantle a new concrete barrier erected by Grand Saga across a toll-free road near the township.
The crowd was attempting to demolish by hand the partly-completed barricades of made-shift steel cables.
About 50 riot police fired at least three rounds of tear gas - each time unleashing about 10 canisters - after water cannons failed to disperse the residents.
During the stand-off, BMC committee chairperson Tan Boon Hwa was arrested by the police.
Two others were also arrested earlier this evening.
According to eyewitnesses, Tan and Segambut member of parliament Lim Lip Eng - who had joined the protestors - were both roughed up by the police during the fracas.
Comment: Why should the police involve themselves in a civil dispute between two parties? The highway concenssionaire apears to have police pRotection. Ber you that the concessionaire turns out tro be a fat cat UUMNOPUTRA being molly-cudled by the gomen.
