“We received a distress call at 12.57pm.
“We immediately dispatched a fire engine and seven personnel to the scene at Kampung Matang Pagar.
“The 29-year-old pregnant woman was hit when a staircase at the construction site collapsed,” he said when contacted on Sunday.
He added that three other men rushed to her aid but died after they were electrocuted.
