The team visited the 47-year-old leading journalist at a private hospital here to record his statement.
Mir refused to record his statement in the presence of the ISI representative, his channel Geo News reported.
The team comprises representatives of Intelligence Bureau, Military Intelligence, Directorate of Inter Services Intelligence, Crime Investigation Department, Federal Investigation Agency and police.
Mir expressed gratitude to all people and said he had reservations over the inclusion of ISI representative and not on the MI in the JIT team, the report said.
His brother has accused "elements in the ISI" of orchestrating the attack on him, a charge denied by the military.
