The West Bengal government has formed a Special Investigation Team (SIT) to probe into the alleged rape-murder of a 10-year-old girl in the South 24 Parganas district's Kultuli area, an official said.
The SIT will be led by Baruipur SP Palash Chandra Dhali, he said.
"We want to assure the locals of our commitment to ensuring justice and punishing those responsible for this crime," the official said on Tuesday.
The state government on Tuesday formed an eight-member SIT to probe the case.
So far, the police have arrested one person in connection with the case.
The court-monitored autopsy indicated that the minor was strangled, police officials said.
Her parents were present during the post-mortem which was recorded on video as directed by the court.
The incident, which occurred on October 5, sparked widespread protests across the state, with locals setting vehicles ablaze, vandalising a police outpost, and blocking roads in the area after the girl's body was found in a pond.
