In a strongly-worded statement issued on Monday, the ED has accused the local Nazat Police Station of registering an FIR incorporating mainly the clauses related to bailable and non-scheduled offences. The ED has also accused the state police of not sharing the copy of the FIR with their officials. According to the ED, after the attack, their officials lodged a complaint at Nazat Police Station for registration of an FIR for offences under Section 307, 333, 326, 353, 392, 395, 397, 149, 148, 186, 189, 426, 435, 440, 341 and 342 r/w Section 120B, 109 and 115 of the IPC 1860.
