Police said the woman jumped onto the road from the pedestrian bridge in front of Phahol Phayuhasena Hospital in Mueang district at about 7am and was struck by the Kanchanburi-Bangkok bus.
The woman’s hospital ID tag identified her as Kanchana In-duom, a resident of Kanchanaburi’s Saiyok district.
Friends told police she’d worked a motorcycle-taxi driver in Bangkok’s Bang Na district but had returned home after contracting tuberculosis.
