Anil Ambani chopper case: Key unanswered questions

On April 23 Bharat Borje , a service technician with Air Works in charge of maintaining Anil Ambani's chopper, found sand and stones in the oil tank of the gear box of the Bell 412 helicopter. Had the 'copter flown it could have almost certainly have led to an emergency.

The next day Anil Ambani's company made the sensational claim that unnamed business rivals were behind the sabotage.

On Tuesday, Borje's body was found near the tracks at Vile Parle. On his person was a note for crime branch officer Sanjay Bhole. Borje's mysterious death points to many key unanswered questions:

Q1) Borje lived in Bhayander and worked at Air Works office in the old airport at Santacruz with an entrance from Kalina. Normally he alighted at Santacruz station, but his body was found at Vile Parle. Why?

Q2) The note found on Borje's person does not speak of suicide but he says, "Me he kelele nahi" (I haven't done this). My parents did not teach me this." Was Borje himself being suspected of sabotage?

Q3) Going further the note says: "Though your investigations are going in the right direction, I saw an accused being beaten up and I got frightened (to tell you anything )." However, crime branch chief Rakesh Maria on Tuesday night told the media that his team got the "relevant case papers only on Tuesday morning and our investigations have JUST begun." Why this discrepancy in the status of inquiry ?

Q4) In his note Borje says that the way officials from Reliance (he does not specify which group) questioned him the previous day led him to believe that "I was being used." Used in which way? Borje's statement was to be recorded by the Crime Branch on Wednesday. Was he being pressured by the company to say certain things?

Q5) A day after the sand and stones were discovered, Anil Dhirubhai Ambani Group lodged a specific complaint that business rivals were behind the sabotage. Did they have any specific tip-off . If so, have they shared it with the investigators?
