"We are likely to summon Hade. As his name surfaced during the probe, we would either question him or just record his statement in the case. We will soon take call on what needs to be done," said Vineet Agarwal, Additional Police Commissioner (Central Region).
Khan, currently lodged in Arthur Road Jail after being arrested for tax evasion, had been apprehended by the city police in December 2008 for allegedly procuring a passport by submitting fake documents.
The Pune businessman was charged with forgery and cheating and later released on bail.
During the probe, a Regional Passport Officer was questioned who revealed that Khan`s passport was cleared on a priority basis after he received a call from Hade, police sources said.
Hade was associated with Mumbai`s Passport Office when Khan was issued the passport.
According to police, Khan had lost his original passport, issued by the Hyderabad`s Regional Passport Office in 2006, when he was in England.
Subsequently, he was given a fresh passport valid for a year by the Indian High Commission`s office in England, using which he went to Switzerland and Canada, police added.
Later, Khan applied for a new passport in Pune.
However, the police found that the billionaire had two other passports procured by submitting fake documents, one issued in Mumbai and the other in Patna.
