A special court here on Friday declined the application of National Investigation Agency (NIA) seeking further custody of Kamal Chauhan, a disgruntled RSS worker arrested by the central agency in connection with the Samjhauta Express blast.
Sending Chauhan to judicial custody, the court posted the case for further hearing on March seven.
The NIA contended during in-camera proceedings that Chauhan had revealed "certain facts" which need to be further investigated.
The NIA also told the court that Chauhan had travelled under fictitious names from Indore to Delhi and was also involved in planting bombs on the train, CBI prosecutors RK Handa and Rajan Malhotra told reporters outside the court.
The investigating agency also apprised the court that Chauhan had given Rs one lakh to another accused in the case, who is still absconding, Handa said.
Chauhan on previous hearings had told reporters outside the court premises that "he knows nothing about Aseemanand". Aseemanand too had told media that he did not know Chauhan.
However, on February 14, Chauhan had admitted before media that he had planted bombs on board Samjhauta Express in 2007 that left 68 people, mostly Pakistanis, dead.
