Sanghai was abducted on December 29 from Kamaladi Ganesthan in the capital.
Sanghai´s family had to pay the ransom to secure his release after the search operation by the Central Investigation Bureau (CIB) and the Metropolitan Police Crime Division failed to yield any result.
The kidnappers had called up the Sanghai family using an Indian phone number and demanded Rs 10 crore.
The police after the investigation assumed that he had been held in the capital itself but failed to find the right location.
When asked about the ransom amount paid and the kidnappers, the police refused to provide information. Details of his release are yet to be known.
Sanghai owns the Arya Pharmceuticals and resides in Dillibazar, Kathmandu.
