Opposition parties on Wednesday alleged that the transfer of a senior CBI official probing the Muzaffarpur shelter home sex scandal case may impact the investigation, a charge denied by ruling alliance partners JD(U) and BJP in Bihar.

"So, after Bihar Governor, Chief Minister Nitish also got CBI SP transferred," RJD leader Tejashwi Yadav tweeted, attaching a document, which he said was a CBI transfer order for JP Mishra, Special Crime Branch SP, who was part of the team probing the Muzaffarpur case.
