Chandranath Rath, the personal assistant to Leader of Opposition Suvendu Adhikari, was shot dead late Wednesday night on National Highway 12 near Madhyamgram in North 24 Parganas district. Police said the attackers had been tracking his movements for at least a week before intercepting his vehicle and firing at close range.

The incident occurred around 11:30 pm when Rath was travelling in a Scorpio towards Siliguri. Near the Doharia area on Jessore Road, bike-borne assailants surrounded the vehicle and opened fire. The driver and two others were also injured.

Eight to fifteen rounds

Initial reports suggested four rounds were fired. But police later revised the count to 8-10 rounds. Hospital sources, however, told reporters that post-mortem examination suggested up to 15-16 bullet injuries. A three-member medical team led by Dr Kallol Ray has been constituted for the autopsy.

Rath sustained gunshot wounds to his chest and head. He was declared brought dead at a nearby hospital.

Movement tracked for a week

Police analysis of CCTV footage from key roads revealed the attackers had monitored Rath’s daily routine meticulously — the routes he took, the vehicle he used, and even the seat he occupied inside the car.

“The assailants knew exactly when and where to intercept him,” an official familiar with the probe said.

Kolkata Police have so far collected footage from eight CCTV cameras. State DGP Siddhinath Gupta is personally reviewing the visuals. A Special Investigation Team is being formed.

Political fallout

BJP workers staged a blockade on NH-12 overnight, demanding an encounter of the attackers. Party spokesperson Keya Ghosh appealed for calm but alleged that back-office BJP workers were being deliberately targeted. “The BJP envisions a government of change, not revenge,” she said.

BJP leader Rakesh Singh went further, demanding the arrest of Chief Minister Mamata Banerjee and party leader Abhishek Banerjee. Union Home Minister Amit Shah is scheduled to arrive in Kolkata later today.

TMC demands court-monitored CBI probe

In an unexpected move, the Trinamool Congress condemned the killing and demanded a CBI inquiry under court supervision. “We demand strict action. The killing of other BJP and TMC workers should also be investigated,” the party said in a statement.

Mother alleges political motive

Hasirani Rath, the victim’s mother, demanded life imprisonment for the killers. “I do not want them hanged, I want life imprisonment,” she said, alleging her son was targeted for political reasons linked to Adhikari’s electoral victory over Banerjee.

Separate shooting same night

About an hour after Rath’s killing, a BJP worker named Rohit Roy was shot and critically injured in Basirhat district. Over the last two days, at least five political workers — two from the BJP and three from the TMC — have reportedly been killed in the state.

A special session of the West Bengal Legislative Assembly has been called for May 25.
