The Enforcement Directorate (ED) has initiated investigation into a money laundering case in which seven persons, including a former BJP member, were arrested by the Kolkata Special task force last week.
They had been caught with Rs 33 lakh, most in new currency notes. The inquiry will look into the source and purpose of the money.
On Friday, police arrested Biswajit Nanda, an associate of Manish Sharma, the former BJP leader arrested in the case. Nanda was caught with a gun, ammunition and three mobile phones.
Last week, the seven accused were caught with cash, illegal arms and several mobile phones. The BJP then had alleged that one of the accused had connections with CM. The TMC has denied this claim.
