Their heroic rescue has reignited debate over the controversial issue of labourers being transported in the backs of lorries

The rare incident occurred on Saturday evening along Tanjong Katong Road South, when a black Mazda was swallowed sideways into a three-metre (10-foot) deep cavity filled with murky water. Video footage circulating on social media showed workers sprinting to the scene and pulling the female driver to safety using a rope.

One of the men involved, construction foreman Pitchai Udaiyappan Subbiah, was seen directing efforts from the roadside. Rather than jumping in, which he said would have left them unable to climb out, Subbiah instructed others to toss a nylon rope into the hole, then helped them hoist the woman up. After the rescue, he lent her his phone to call her daughter.
