CBI has sought customs and central excise officers on loan to help it investigate complex cases, including those on financial crimes.

CBI Director Anil Sinha has written to Central Board of Excise and Customs (CBEC) seeking nominations of eligible officers.

The agency which is entrusted with probe of various economic offences lacks officers with expertise in taxation and accounting related matters which are must for deciphering white-collar crimes.

"As you are aware that Central Bureau of Investigation is a predominantly deputationist organisations, hence we keep requiring services of officers from different organisations for induction.

"This would be advantageous for both the organisations," Sinha said in a letter to CBEC chairman Kaushal Srivastava.

The Bureau would utilise the expertise and experience of the officers for investigation of complex cases and after their repatriation the experience gained by them in CBI would benefit the parent organisations, Sinha said seeking nomination of Indian Revenue Service (Customs and Central Excise) officials.

The CBI is looking on deputation basis suitable and eligible officers with impeccable integrity and outstanding annual confidential reports to fill nine posts in the rank of Superintendents of Police (SPs). These posts are to be filled by officers other than those belonging to Indian Police Service (IPS).
