At least seven migrant workers from Bihar and North Karnataka were killed on 2 July after a massive boulder crashed down at the Kaveri Crusher stone quarry unit in Madapatna village, Bengaluru South taluk, early in the morning. Several others sustained injuries, and rescue teams feared additional workers remained trapped beneath the debris, with the death toll expected to rise. The incident falls under the jurisdiction of Tavarekere Police Station.

What Happened at the Site

According to Yeshwanthpur MLA S.T. Somashekar, approximately 10 workers were at the quarry preparing for blasting operations when the accident occurred. He alleged that a licensed quarry operator working at a site roughly 100 feet above the location was conducting operations when a massive boulder — along with a Hitachi excavator — came crashing down onto the workers below. Seven workers died on the spot, and Somashekar said he was also receiving information that an eighth injured worker had subsequently succumbed.

Chief Minister Condoles, Warns Quarry Owners

Karnataka Chief Minister D.K. Shivakumar expressed profound grief over the tragedy. 'The boulder collapse at the crusher unit in Madapattana, Bengaluru South taluk, in which seven workers lost their lives, has caused me profound grief,' he said. Shivakumar added that ensuring worker safety in stone quarries is the responsibility of quarry owners, and that the government would take appropriate action against those violating safety regulations.

MLA Alleges Illegal Quarrying, Demands FIR Against Officials

Somashekar alleged the accident was the direct result of rampant illegal quarrying carried out with the alleged collusion of officials from the Mines and Geology Department, the Forest Department, the Police, and the Karnataka State Pollution Control Board. He demanded that officials from all four bodies be named as accused in the FIR. 'Officials should be named as Accused No. 1, Accused No. 2 and so on. Only then will such deaths stop,' he said.

Somashekar further alleged that the quarry where the accident occurred belongs to the family of the President of the Karnataka Stone Quarrying Owners' Association, warning that influential parties would attempt to suppress the matter. He said he had repeatedly raised concerns about illegal quarrying in the area — including before the Petitions Committee on three occasions — and had previously flagged the issue after the death of a pregnant leopard in the same region. He alleged that even after an inquiry was ordered in that case, the matter was hushed up.

Deputy CM Seeks Detailed Report

State Deputy Chief Minister G. Parameshwara said he would seek a full report on the incident. 'If there are aspects that come under my department, appropriate action will be initiated. There are several illegal quarries operating in the state. We will verify the facts and take action against illegal quarrying sites wherever violations are found,' he said. Quarry licences, he noted, are issued by Deputy Commissioners and the Mines and Geology Department.

What Comes Next

Somashekar said he would meet Chief Minister Shivakumar to press for strict action, insisting that accountability mattered more than compensation. 'More important than compensation is action against illegal and negligent quarrying. The quarry owners must be arrested, and compensation should be recovered from them,' he said. The identities of all the deceased had not yet been fully established as of the time of reporting. Families of the victims and labour rights advocates will be watching closely whether the government files an FIR naming officials, or whether — as the MLA alleged has happened before — the case is quietly set aside.
