Inspector-General (CID) MP Dwivedi of Madhya Pradesh police, who is the chief investigating officer in the case, said on Sunday that he is looking into all possible angles, ‘‘including Gujarat.’’

There have been reports that the woman figuring in the CD is from Vadodara — the family is untracable since the scandal broke — and that the CD was the result of a sting operation masterminded by Joshi’s rivals in Gujarat.

The girl’s family is said to have old connections with the Rashtriya Swayamsevak Sangh (RSS), and Joshi is said to have lived with them whenever he visited Vadodara on political assignments. Dwivedi said, ‘‘yes, we know of this possible Gujarat and Vadodara connection. We will look into it, but at this early stage, I would not like to comment on the specifics of it.’’
