The tranquil suburb of Bandar Mahkota Cheras (BMC) descended into chaos last night when police doused some 500 residents with water cannons and fired dozens of tear gas canisters into the crowd.

During the melee, Segambut member of parliament Lim Lip Eng and BMC Open Road Committee chairperson Tan Boon Hwa were allegedly assaulted by plainclothes police officers.
