Income Tax Department — Income tax defaulter

Address:

Thane, Maharashtra, 401504

One of my colleague who is getting salary from NPCIL & also pro rata pension from DAE
But he is showing only salary in IT returns. The regular pension getting through UBI since 1998, he is not showing to income tax department. This year he got the pension arrears more than 5 laces (since 2006) but till date he did not show to income tax department. In previous years returns he did not show even his pension account. Is it any way to catch hold of such type of culprit?

The details of income tax defaulter is give bellow.
