A joint search operation of civil and military personnel has been on since last night to recover the bodies, SSP Moradabad Luv Kumar said today.
Due to heavy rainfall, the road was flooded due to which the 4-feet wide and 15-feet deep uncovered pit, which was dug up to lay down sewerage pipelines, was unnoticeable.
Kumar said that as per witnesses, an unidentified woman and her son fell into the pit at Indira Chowk here. A youth, who jumped into the pit to rescue, too went missing.
Prem Assudani, Managing Director of UP Jal Nigam, which is involved in the sewer line work, said a high-level inquiry has been initiated into the matter and those found guilty will be punished.
District Magistrate Deepak Aggarwal said the search operation was continuing on war footing.
