Investigations have also progressed against medical practitioner Durga Prasai, who is in police custody, for banking offenses and money laundering. The Central Investigation Bureau (CIB) of the police has started an investigation into both crimes against Prasai. CIB has started interviewing him from Monday.

Prasain is in the custody of District Police Complex Kathmandu for the Tinkune incident of Chait 15. The CIB took them from the premises to the district attorney's office and started the initial statement. The CIB had obtained an arrest warrant against him from the Patan High Court. SSP Hovindra Bogti of CIB informed that the investigation has been started against Prasai in money laundering, Rashtra Bank Act and related banking offences.

Nepal Rastra Bank sent a letter to CIB to investigate him after he was accused of misappropriating the loan taken from the bank for running various businesses including medical college and laundering assets under the same guise. Last week of November and sending letters on January 23, Rastra Bank asked to investigate the transactions related to Prussia. Apart from this, a complaint was filed in the CIB on the allegation that Prasain had threatened businessmen and bank managers by forming a criminal group. SSP Hovindra Bogti of CIB said that based on the letter of Rashtra Bank and the complaint received from the victim, investigation has been started against Prasai on charges related to banking offenses and money laundering. On March 17, the Patan High Court granted permission to arrest Prasai.

Prasain is the director of B&C Medical College and Hospital and Purvanchal Cancer Hospital in Birtamod, Jhapa. Preliminary investigation shows that there are 31 different companies including B&C Medical College and Hospital in the name of Prasain, his family members/relatives. According to CIB's investigation, 7 billion 25 million 87 million rupees of loans from 5 different banks in the name of these companies have been outstanding till last October.

Prasai has been reported to have taken a loan of Rs 125 million from the then NCC Bank (later merged with Kumari Bank) in the name of Purvanchal Cancer Hospital, Rs 5 crore from Nepal Investment Megha Bank Limited in the name of Hotel Atrium and Rs 10 crore from Goodwill Finance Limited in the name of UA Medico Supplies and Equipment Pvt. He is being investigated for money laundering on the allegation of suspicious transactions through various parties to hide the profit from banking loan investment.

Since 2021, foreign currency amounting to 10.5 million rupees has arrived in the accounts of Prasai and his relatives/relatives from various countries, and the National Bank has already written to the CIB to investigate with the suspicion that this amount may be a suspicious transaction.

'Prasain and his family affiliated firms and companies have used the loan funds taken from various banks and financial institutions for the purposes for which they were taken, but used them elsewhere without using them for the same purpose, used other loan funds to repay loans from various banks and financial institutions, misused loans by using loan funds for other purposes than those mentioned when taking loans from banks and financial institutions, loans taken from banks should only be used for business and business income should be used to pay off loans. and provided to his affiliated companies," it is said in the evidence presented by the police for investigation on him, "It seems that the arrears and interest payments of the loans paid to B&C Medical College Teaching Hospital and Research Center Pvt Ltd and Purvanchanal Cancer Hospital Pvt Ltd for four years are not regular. CIB officials have said that Prasain himself is still present, keeping him in the center of this investigation. Section 8 of the Banking Offenses and Punishment Act 2064 states that 'loans taken from banks/financial institutions' should not be misused. It is said in that section, "No one should misuse the loan by using it elsewhere without using it for the purpose for which he has taken the loan facility from the bank or financial institution." Prasai is accused of using the loan against the same section.

Prasain, who was arrested on charges of inciting violence in Tinkune during the royalist demonstration on Chait 15 and causing human and material damage, is in the custody of the District Police Complex, Kathmandu. Prasai, who absconded after the Tinkune incident, was arrested on March 28 from Assam, India. Police are investigating Prasai with permission from District Court Kathmandu for crimes against the state and organized crime. Two cyber crime related cases are also pending against Prasai in District Court Kathmandu. He is a defendant who is out on bail in both cases.

He was released on October 15 after posting a bond of 1 lakh in a case related to cyber crime filed against him by the District Public Prosecutor's Office Kathmandu. On October 6, 2081, he was arrested from his residence in Bhaktapur on charges of cyber crime, and was released on bail on October 15, 9 days later. Both the cases are pending in the Kathmandu court. The investigation of the three-cornered incident has not been completed. While the case of cyber crime is in the court and the investigation of the Three Kune incident is underway, the investigation into money laundering and banking crime has also started against him.
