Deputy Bangkok Metropolitan Administration (BMA) governor Sakchai Boonma inspected an 80-centimetre-wide sinkhole on August 19, which was later found to be on top of a 3-by-5-by-1-metre subsidence on Rama IV Road’s inbound lane. He ordered city workers to urgently repair the sinkhole.

Some 30 motorcycle taxi drivers were rounded up by authorities on Thursday morning at a stand on Rama 4 Road in Bangkok's Khlong Toei district as part of an investigation into illegal operators.
