The order issued today also directed the branches across the country to have one-fourth of their total strength to be specialised investigation officers.
"Linking the transfer policy with promoting specialised skills, the normal branch shall have 25 per cent of specialised Investigating Officers (I0s) while Central Units shall have 50 per cent specialised officers," it said.
The order said after completing the maximum tenure by a specialised IO, he/she will be considered to be transferred either to the same domain at different station or to the branch having investigation of similar nature, it said.
"The performance and aptitude of officer will be basis on which concerned Head of Branch (HOB) and Head of Zone (HOZ) will recommend the name for specialisation in a particular domain," the new policy unveiled by the agency today said.

The agency will also give a chance to all its investigating officers to specialise in two areas during his service tenure.
