The agency has booked M K Singh Senior Section Engineer of the Research Design and Standards Organisation (RDSO), Gee Cab Industries Limited and its director Roop Kumar Lal along with unidentified public servants and private persons.
It is alleged that the Southern Railway had placed an order for the purchase of 280.1 km of underground telecom copper conductor cable for a value of Rs 5.43 crore.
The CBI has alleged that the company supplied only 277.6 km of the cable which was duly inspected and certified by Singh.
"It also revealed that the sample cable checked during the joint check was tested and passed by the RDSO during their inspection and sent to the consignees of Southern Railway for laying," it alleged.
The agency has taken note of the complaint from the deputy CVO of the Southern Railways and filed an FIR for allegedly causing a wrongful loss of Rs 5.43 crore.
