Kolkata, May 13 -- The Central Bureau of Investigation (CBI) on Wednesday morning conducted a 3D mapping of the crime scene in the murder case of Chief Minister Suvendu Adhikari's personal assistant, Chandranath Rath.

According to sources, the 3D mapping of the crime scene and adjacent areas was carried out to assist CBI officials in the investigation and in the reconstruction of the crime in the near future.

Earlier on Tuesday, after taking over the probe, the CBI's Special Investigation Team (SIT) visited the crime scene along with experts from the Central Forensic Science Laboratory (CFSL).

Rath was shot dead by unidentified assailants on May 6 at Doharia in Madhyamgram while returning home.

During the investigation, police arrested three persons from Bihar and Uttar Pradesh. Sources said two of the accused - identified as Mayank Raj Mishra and Vicky Maurya - were detained from Buxar in Bihar, while another accused, Raj Singh, was detained from Ballia in Uttar Pradesh. The trio was brought to Madhyamgram and formally arrested on Monday morning.

Investigators found that the vehicle used by the accused had been spotted near Barasat Rail Gate No. 11. The car allegedly proceeded towards Birati, where Mayank got down, before taking a U-turn towards Madhyamgram.

Following a recommendation from the state government, the CBI took over the investigation and formed a seven-member SIT led by Deputy Inspector General (DIG) Pankaj Kumar Singh. The probe is being supervised by the Joint Director of the central agency in Kolkata.
