A special court on Friday remanded in judicial custody for 13 days, the 10 accused, arrested in connection with the murder of senior journalist Jyotirmoy Dey.
"The accused were produced before the Maharashtra Control of Organised Crime Act court, which remanded them in judicial custody till September 30," a crime branch official said.
The police custody of Paulson Joseph, the 10th suspect arrested on September 5 in the case, was over on Friday following which he, along with the nine others, whose judicial custody had also ended, were produced in the court.
"Joseph was sent to judicial custody as his police custody was not sought by us, whereas judicial custody of nine others was extended," the official added.
Dey, editor (investigations) with the city-based English tabloid, Mid Day, was shot dead by four motorcycle-borne assailants in suburban Powai on June 11, police said.
Police had claimed that the scribe was eliminated at the behest of underworld don Chhota Rajan, who paid Rs 5 lakh to the accused. However, investigators said the motive behind the killing was not yet clear.
Other nine arrested accused include a builder Vinod Asrani and sharp shooters, police said.
Joseph is the same person who had organised a Christmas-eve bash at Chembur in 2009 that saw five policemen, including a deputy police commissioner, suspended as the cops, were caught on camera partying with the gangsters.
