Senior journalist Jigna Vora and Chhota Rajan aide Paulson Joseph, who were arrested in connection with the murder of Mid Day journalist J Dey, have been sent to police custody till December 5.
The other accused will be under judicial custody until December 5.
The court also rejected a police request to conduct a narco test on her.
Vora, who was arrested last month and sent to police custody till December 1, works for the Asian Age newspaper in Mumbai.
She is facing charges of aiding and abetting in the murder of Dey.
Dey was shot dead by in broad daylight by four motorcycle-borne assailants in a crowded street in suburban Powai on June 11 this year.
Vora has been arrested for allegedly giving details like Dey's motorcycle registration number and his address to fugitive underworld don Chhota Rajan, who is accused of masterminding the murder.
She was arrested under the Maharashtra Control of Organised Crime Act (MCOCA) and will be tried for murder and conspiracy like the 10 other accused who have been arrested in the case, the police said.
Mumbai Police Commissioner Arup Patnaik is on record as saying that the Dey murder case is a sensitive one and that the police is pursuing leads and investigations very cautiously.
He said that as far as Vora was concerned, the state police had prima facie evidence that she was involved, and therefore, had arrested her at her Ghatkopar residence on the morning of November 25.
The Asian Age has stood behind Vora, a crime and court reporter, saying that she was innocent and of impeachable integrity.
Dey was Investigations Editor with the MidDay, and spent most of his reporting career revealing the goings-on in the Mumbai underworld for several newspapers, including the Indian Express and the Hindustan Times.
He wrote ''Zero Dial: The Dangerous World of Informers'' and ''Khallas''.
The books are considered to be among the most authoritative writings on the Mumbai underworld.

Vora has been booked under several charges, including Sections 302 (murder), 120 (B) (conspiracy), 34 (acts done by several persons), 201 (giving false information) of the IPC, Sections 3, 25 and 27 of the Arms Act, Sections 37 (1) (A) (prohibiting public gathering of more than five persons), 135 (burning effigy of the central government) of the Bombay Police Act and Sections 3(1), 3(2), 3(4) (organised crime) of MCOCA.
