Some police encounters that stunned India.
Gangster Chhota Rajan, prime accused in the journalist J Dey murder case, thought that the veteran crime reporter was working for his rival Dawood Ibrahim and Pakistan's spi agency Inter-Services Intelligence, according to the chargesheet filed by the Central Bureau of Investigation.
The court will on Tuesday hear arguments on the quantum of sentence to be awarded to the convicts.
The court said that Rajan suspected that J Dey was working for Dawood Ibrahim and the journalist was showing him in a poor and weak position.
Dey, a veteran crime reporter, had planned a book, titled 'Chindi -- Rags to Riches', wherein he was going to write the stories of 20 gangsters with humble origins.
Rajan is lodged in Tihar Jail in New Delhi. The other three persons, who were out on bail, were taken into custody on Monday after the verdict was announced.
Security agencies got clues about his whereabouts following the arrest of one of his close associates in Mumbai recently, the source added.
