A Special CBI court on Friday remanded to 14-day judicial custody the three accused arrested in connection with alleged corruption in supply of packaged drinking water in Rajdhani and other superfast trains.

Special CBI judge Vinod Kumar remanded two senior rail officers — Sandeep Silas and MS Chalia — and a businessman — Sharan Bihari Agrawal — to judicial custody after CBI submitted that they were not required for further custodial interrogation as of now.

"All the three accused are remanded to 14-day jusicial custody," the judge said.

The accused were produced before the court after completion of their five-day CBI custody.

The probe agency has said that Silas and Chalia conspired with Agrawal and instead of taking Rail Neer, they had allowed some private firms to supply water in the trains which resulted in a loss of Rs 6.25 crore to the exchequer.

It said that searches were conducted during the probe in which approximately Rs 28 crore cash was recovered out of which around Rs four lakh was counterfeit.

Silas, a 1984-batch Indian Railway Traffic Service(IRTS) officer, and Chalia of 1987 batch officer were taken into custody on Saturday night along with Agrawal, owner of R K Associates, in connection with the scam.

Besides them, the CBI has also registered case against seven private companies – RK Associates Pvt Ltd, Satyam Caterers Pvt Ltd, Ambuj Hotel and Real Estate, PK Associates Pvt Ltd, Sunsine Pvt Ltd, Brandavan Food Product and Food World – under the provisions of Prevention of Corruption Act.
