"The advocate requested me that since it was a serious threat to his (Modi's) life, I should meet Lalit Modi briefly. As per the lawyer's insistence, we met, albeit briefly, wherein Lalit Modi sought the Mumbai Police's help as he and his family were being threatened by the underworld," the statement said.
Maria said he "categorically" informed Modi that Mumbai Police has no jurisdiction in London and that he should return to Mumbai to lodge a formal complaint.
"Lalit Modi repeatedly kept requesting for Mumbai Police's intervention against the underworld. I reiterated to Modi and his lawyer that it was imperative for Lalit Modi to return to Mumbai for the Mumbai Police to initiate any inquiry. Thereafter, the meeting lasted barely for 15/20 minutes," the Police Commissioner said.
"I also maintained the requisite confidential record of the same. Besides, the Anti-Extortion Cell of the Mumbai Police was also given in writing the details of what had transpired in the meeting for discreet inquiry at their end," he added.
