V K Jain additional sessions judge on Thursday remanded R Perumalswamy, personal assistant to former Union Minister of State for Finance Gingee Ramachandran, Chennai-based chartered accountant A Krishnamurthy and Indian Revenue Service official Anurag Vardhan, facing charges in the cash-for-transfer scam, to judicial custody for 14 days.

Special Judge V K Jain, before whom the accused were produced on expiry of their police custody, sent them to Tihar Jail till June 19.

Jain heard the case as the trial judge Prem Kumar was on leave.

Meanwhile, Central Bureau of Investigation on Thursday moved the court to obtain custody of documents allegedly recovered during the raids carried out on Krishnamurthy's Chennai premises.

The agency had deposited these documents before a Chennai court where the accused was produced after his arrest.

The application would come up for hearing on June 7.

Asked if CBI had enough material to interrogate Gingee Ramachandran, A S Cheema, advocate of CBI, refused to comment on the matter saying the case was under investigations.

CBI had arrested Perumalswamy on charges that he had accepted bribe from Vardhan for giving him a choice transfer to Mumbai.

Krishnamurthy, the agency alleged, acted as the main conduit in the conspiracy.
