West Bengal Police on Sunday, 12 July elevated the investigation into the alleged rape and murder of a 12-year-old girl at Baruipur in South 24 Parganas district, appointing Santanu Mukhopadhyay, a Deputy Superintendent of Police (DSP)-rank officer, as the new investigating officer (IO). It is the second time the IO has been changed since the case was registered, marking a clear escalation in the seniority of the officer handling the probe.

A Third IO in Eight Days

The victim's body was recovered from a pond in the Suryapur area under Baruipur on the morning of 5 July. Inspector Diganta Mondal of the Baruipur Police District was initially appointed IO, given that the crime scene fell within his jurisdiction. He was subsequently replaced by Jayanta Poddar, the former inspector-in-charge of Baruipur Police Station. Mukhopadhyay, a DSP-rank officer, is now the third person to lead the investigation — and the most senior yet.

What Prompted the Latest Change

The reshuffle was announced just one day after the Chief Minister visited Baruipur and assured the victim's family of a prompt investigation and early conviction of all accused. The back-to-back IO changes suggest mounting pressure on the state police to demonstrate accountability in a case that has drawn widespread public attention. Notably, the two previous IOs were both inspector-rank officers; the appointment of a DSP signals a formal upgrade in the probe's priority level.

Arrests and Encounter Death

So far, four persons have been arrested in connection with the crime against the minor girl. One of them, Pravas Mondal, was killed in an alleged encounter last week after he reportedly attempted to flee from police custody by snatching a firearm from an escorting officer. The circumstances of the encounter are part of the broader investigation.

Two Parallel Cases Under Probe

West Bengal Police are simultaneously investigating two related cases that emerged in the aftermath of the body's discovery. The first involves the mob lynching of Indrajit Tanti, a 26-year-old youth, on the afternoon of 5 July. According to police, a group of local residents — protesting after the recovery of the girl's body — allegedly and deliberately misidentified Tanti as an accused and killed him. Five persons, reportedly the alleged masterminds behind the lynching, have been arrested.

The second case concerns large-scale violence that broke out in the area on Sunday afternoon, during which railway tracks and police vehicles were reportedly vandalised and police personnel were attacked and injured. 42 people have been arrested in connection with the violence so far.

What Comes Next

With a DSP now at the helm, investigators are expected to consolidate all three parallel cases — the rape-murder, the lynching, and the violence — under a more coordinated framework. The pace of the probe and the timeline for filing a chargesheet will be closely watched by the victim's family and civil society groups demanding swift justice.
