Gopal Dass crossed over to India from Pakistan April 7 at the Attari checkpost after his 27 years' incarceration in a Pakistani jail on charges of being a spy.
Pakistan will release the 89 Indian prisoners, including fishermen, as a goodwill gesture that would boost ties between two countries, the News International quoted Geo News as reporting.
A Foreign Office statement said the freed Indian prisoners would be handed over to Indian authorities April 15.
India, during the secretary level talks early this month, provided Pakistan a list of its citizens detained across the border, the statement added.
