The police said they received a call about the body at 7.33am. Paramedics from the Singapore Civil Defence Force (SCDF) also responded to the case a few minutes later at the canal between McNair and St George's roads.

SCDF rescuers then manually retrieved the body from about 2 metres from the river bank and pronounced the woman dead at 8.28am.

The police have classified the case as an unnatural death and are investigating.
