Commissaire de police
The building collapse appeared to be the result of poor-quality building material and having been "weakly built", according to Police inspector Digamber Jangale and Police commissioner K.P. Raghuvanshi. Lawful building construction in Thane district requires blueprints to be filed and approved by municipal agencies and permits obtained to connect electricity, water and sewage services. The builders did not file the blueprints in this case.
