MIDNAPORE: Five agencies from both the Centre and state governments, including the cabinet secretariat’s security wing and the Intelligence Bureau, on Tuesday began a probe into the collapse of a tent at PM Narendra Modi ’s rally in Midnapore .

Bengal agencies and BJP started a blame-game — trying to fix responsibility on each other for the accident — with one particular set of circumstances serving to highlight the politics that followed the incident that left 99 people injured on Monday.

Bengal cops called Rajiv Singh, owner of the Kolkata-based JN Decorator (which constructed the tent that collapsed), to Midnapore for questioning. Singh reached the Midnapore Police Lines in the afternoon. But several cops — who were supposed to question Singh — were, instead, closeted with investigators from central agencies for a large part of Tuesday, which they said “delayed” their probe.
