Special Judge Sangeeta Dhingra Sehgal also posted the hearing on his bail application for December 4.
The IAS officer, who was working as a Director Internal Security in Ministry of Home Affairs, was produced in court after the end of his six-day police remand.
He was arrested by the Special Cell of the Delhi police on November 23 after two days of extensive interrogation in detention.
The police sought his further remand on the ground that they were yet to recover two out of the four mobile phones that he was allegedly using to maintain contacts with unauthorised persons.
Public prosecutor Rajeev Mohan said that except one official phone, three mobiles were obtained on fictitious identity.
Advocate O P Wadhwa, appearing for Singh, opposed the application on the ground that he had already been in the custody of the investigators for six days.
After hearing the arguments, the court sent the accused IAS officer to judicial custody for 14 days.
The court, meanwhile, put the hearing on his bail application for December 4.
The court also remanded Vineet Kumar, an associate of Singh to 14-day judicial custody, declining his bail application.
Kumar, Chairman-cum Managing Director of Temptation Foods Private Ltd, was arrested on November. He allegedly provided lodging facility to the IAS officer after his transfer from West Bengal to New Delhi in January this year.
Earlier, the prosecution had submitted that a sum of Rs 21 lakh was transferred to an account opened at a branch of Bank of Maharashtra in the name of Singh's spouse, a house-wife, in the address of the guest house at posh Greater Kailash enclave here.
The said bank account still had balance of Rs 15 lakh, prosecution had claimed.
It had also said that Singh had leaked information pertaining to a US-based telecom company, Telcordia, for illegal gratification.
Singh and Kumar were arrested after a case was registered under various provisions of the Prevention of Corruption Act and the Indian Penal Code dealing with criminal conspiracy and destruction of evidence.
