The Income Tax Department and National Investigation Agency personnel on Monday night seized cash worth Rs 2,500 crore and gold from four trucks here and detained 47 people.

The trucks were apprehended from outside Mumbai Central railway station. According to reports, the cash was to be transported to Ahmedabad on Gujarat Mail.

In an interesting twist in the case, it has been revealed that an Inspector stationed at South Mumbai's VP Road and his colleagues had escorted the trucks to station.

The joint operation by more than 100 officers was carried out at around 9 pm, when the four trucks reached outside the Mumbai Central station to unload the suitcases.

Those detained with around 150 suitcases of cash are being grilled.

Gold and jewellery have also been seized, added reports.

The IT officials are still counting the cash at their head office in Scindia House in Ballard Estate in south Mumbai, which houses many other central government offices.

The NIA sleuths got information about the transfer of cash and gold from the biggest unofficial market of Angadias, carriers of cash and gems.
