Tej Pratap Yadav, the elder son of RJD national president Lalu Yadav, had vacated the bungalow a few days ago after repeated notices were sent by the state government. He had claimed that Chief Minister Nitish Kumar and Deputy Chief Minister Sushil Kumar Modi had "let loose ghosts inside the house".
"Our attention has been drawn towards the matter through media reports. It is a serious matter as the bungalow is located in a VVIP area and hence, a probe will be conducted," Minister for Building Construction Maheshwar Hazari told news agency PTI.
Tej Pratap Yadav, who has been in the news for making acerbic attacks on his political adversaries, lost the health minister's post in July last year following Chief Minister Nitish Kumar's exit from the Grand Alliance, comprising the JD(U), RJD and Congress.
He later formed a new government with the BJP and returned to the NDA.
Incidentally, Tejashwi continues to occupy the bungalow adjacent to the chief minister's residence that was allotted to him when he was the deputy chief minister.
