Owner of Rotomac pens, Vikram Kothari and his son, Rahul have been taken into custody by Central Bureau of Investigation (CBI), over looting of nationalised banks of Rs. 3,000 crs. The arrest became necessary as both father, son duo were not cooperating in the investigation, the CBI officials said. They will be produced in the court soon. Kothari's lawyer said that he will file a counter petition, opposing remand to CBI. What the court has to say remains to be seen.
