The Board reportedly found that several irregularities had been committed by it while it was operational.
After the Board of Officers completed its assessment into the operations of the unit, the Army had recommended to the Defense Ministry to recommend a CBI probe to look into the alleged irregularities committed by it.
The unit has also been accused of indulging into activities for destabilizing the Jammu and Kashmir government.
The existence of the TSD came to light after allegations were leveled against it for tapping the phones of senior Defense Ministry officials at the height of the age controversy involving Gen VK Singh.
