Four more officers of the Hyderabad-based construction company in-charge of building the Vivekanda Road flyover, a portion of which collapsed last week, were arrested on Monday.
IVRCL Director Operations Gopal Krishnamurthy, Deputy General Manager of Project Monitoring Cell (PMC) S K Ratnam and senior engineers Shyamal Manna and Bidyut Manna were arrested after a long grilling session at the Kolkata Police headquarters on Monday.

Police have registered a case against the construction firm and sealed its office in the city.
Another Assistant Vice-President of PMC Ranajit Bhattacharjee, who was injured and now hospitalised after Thursday's mishap, is also under police scanner.
"Bhattacharjee was reporting to Ratnam... So we need to look into that also. Let him get out of the hospital. We will also look into his roles," the officer said.
