Sonal Mohan Agnihotri, a senior police official, made the submission before Special CBI Judge Vinod Kumar and provided details of Rajan's extradition and arrest in Bali on the basis of a Red Corner Notice issued by the Interpol.
The officer was deposing as a prosecution witness in a fake passport case against Rajan and three former passport officers.
The court, which fixed the matter for tomorrow for further proceedings, had earlier framed charges for alleged offences of cheating, forgery and criminal conspiracy against Rajan and others in the case. The accused had pleaded not guilty and claimed trial.
The court had ordered trial in the case on daily basis noting that Rajan was in judicial custody for a long period and trial should be started on a day-to-day basis.
Besides Rajan, the court also put on trial three retired public servants.
The four accused have been charged for alleged offences under sections 420 (cheating), 471 (using as genuine a forged document), 468 (forgery for purpose of cheating), 467(forgery of valuable security or will), 419(cheating by impersonation) and 120B (criminal conspiracy) of the IPC and section 12 (offences and penalties) of the Passport Act.
The CBI had earlier told the court that the government officials had conspired to issue the passport to Rajan in name of one Mohan Kumar, a non-existent person in complete violation of procedures.
It had told the court that Rajan, currently lodged in Tihar Jail under judicial custody, was accused in several cases of heinous nature involving charges of murder and extortion and when in 1995, a Red Corner Notice was issued against him, he had used a new identity to escape.
According to another journalist, Rajan told him that Dey
A close friend of Dey's told the investigators that Dey had told him that Rajan was calling him frequently. He found the gangster to be very "polite".
"I told him...One should be alert...Because dons are polite when they want to deceive someone," he told CBI.
On the day of the murder, Dey had told this witness on phone that Rajan had again spoken to him recently.
As Dey was worried about getting frequent calls from Rajan, the witness suggested that he should see if he had made any mistakes (so as to offend the gangster).
According to a police constable, who is a witness in the case, Chembur's son Sanjay told him Dey wanted to get Rajan killed and was supplying information to Dawood gang.
According to CBI, Rajan was upset with Dey over certain articles written by him, and also because Dey's planned book described Rajan as "chindi" (a small fry).
The book, 'Chindi -- Rags to Riches', was to tell stories of 20 gangsters with humble origins. It was supposed to describe Dawood, Rajan's friend-turned-foe, as being superior to the gangster.
The 300-page charge sheet against him was filed at the special Maharashtra Control of Organised Crime Act court here last week.
The first charge sheet filed in the case in 2011 names Satiah Kaliya, Abhijeet Shinde, Arun Dake, Sachin Gaikwad, Anil Waghmode, Nilesh Shendge, Mangesh Agawane, Vinod Asrani, Paulson Joseph and Deepak Sisodia (all arrested).
Another charge sheet was filed against Vora next year. Accused of instigating Rajan against Dey owing to her own professional rivalry, she is currently on bail.
