Revenue and customs officials of this district are investigating whether Rs 5000 crore had been brought in a container in a ship to the port here.
Officials said today three ships have been searched but nothing has been found so far.
District Collector M Ravikumar said they were verifying the information whether currency had been brought through Tuticorin port and whether it had been offloaded.
