A joint investigation team (JIT) has been constituted to question Dr Asim Hussain over allegations of providing medical assistance to militants.
According to reports, the newly formed JIT, headed by SSP South Dr Farooq, would begin probe in the next two days.
No official of the Federal Investigation Agency (FIA), National Accountability Bureau (NAB) and anti-corruption unit is included in the team.
However, for the first time, two gazetted officers of the Rangers intelligence service are part of the JIT.
