The bus is most likely an OS bus back for SLBP, as there are no
revenue SBST service that would either go straight along
International Road at that intersection, or do a turn from Jln Boon
Lay into International Road. And the cyclist and the bus was found
on International Road towards SLBP after the junction, so that
rules out the possibility of a svc 249 bus killing the cyclist.
Anyway, the accident happened at 12.10am, and that is the time
where buses will progressively return to the depot.
As for the bus, it is an unknown KUB Euro IV with ad, rego ended
with the letter "H".
