Four workers are electrocuted during borewell drilling work near a resort in Mamallapuram, Tamil Nadu, according to reports from multiple outlets. The incident occurs while drilling equipment is being operated at the site. Authorities and preliminary accounts describe how the drilling process involves contact with an overhead high-voltage power line. In one account, an iron rod used for the borewell comes into contact with the overhead line during the operation. Another report similarly says the accident follows when the drilling equipment reaches or contacts the high-tension line. One worker is reported to be critically injured, while three others are also electrocuted. Emergency responders reach the location and provide immediate assistance, with injured personnel taken for medical evaluation. Police and investigators are conducting preliminary inquiries into how the contact occurred, including whether safe distances from power infrastructure were maintained and how the drilling equipment was positioned during the work.
