The court of R K Singh extended the judicial remand of Ranjan, who appeared before the court.
He was accused of abetting suicide of Nirupama, whose body was found at her home here on 29 April 2010.
Earlier, Ranjan's bail plea had been rejected by the Jharkhand High Court after he approached it soon after the Chief Judicial Magistrate, Koderma, issued warrants against him in connection with Nirupama's death.
The warrants by the local court were issued on the petition submitted by the police praying for issuance of warrants against him under section 306 (abetting the commission of suicide).
Initially a case of murder was filed against Nirupama's mother Sudha Pathak and she was arrested. She got bail after remaining three months in judicial custody in 2010.
After Nirupama's body was found at her native place at Chitra Gupta Nagar Colony at Jhumri Telaiya in Koderma town, Ranjan accused the family of killing their daughter after allegedly opposing their marriage.
The police, however, had said in its investigation that a forensic laboratory in Kolkata found that the suicide note was signed by Nirupama, and ruled out murder.
