KOLKATA: : A day after the murder of Suvendu Adhikari’s aide Chandranath Rath, Bengal BJP seniors appealed for calm and restraint on Thursday. Calling the killing heartbreaking, a distraught Adhikari, who reached Barasat medical college late Thursday, said, “Politicians often depend on key people who are not involved in politics”. Bengal had seen “politics of revenge”, Adhikari said, adding, “BJP is not jumping to conclusions immediately. The swearing-in ceremony is due in a few days. We will ensure the killers are punished.” Union minister Sukanta Majumdar, who accompanied Adhikari at the hospital, said DGP Siddh Nath Gupta had reached the spot. Speaking to ANI, BJP state president Samik Bhattacharya said, “Was this carried out to send a political message or is there some other motive, or is it an act of vendetta? The probe is underway, and truth will come to light.”
