It said the action came in an ongoing case against members of the TPC.
The National Investigation Agency had filed a charge sheet against 16 TPC members, including 2 employees of Central Coalfields Limited (CCL) and some businessmen, in a special NIA court in December last year.
The NIA said two plots of land and a double-storeyed house belonging to TPC operative Binod Kumar Ganjhu, besides five vehicles worth Rs 31 lakh have been attached.
The agency has also seized 10 vehicles, including a JCB loader, belonging to TPC operative Bindeshwar Ganjhu; 10 trucks valued at Rs 1.61 crore, four vehicles belonging to Pradeep Ram and three acres of land worth Rs 4 crore of TPC commander Akraman.
"All the properties seized/ attached have been acquired by TPC members using terror funds collected by way of levy/ extortion," NIA Spokesperson said.
