The `Balasahebanchi Shiv Sena` party on Wednesday demanded a probe either by CID or CBI into "fake" affidavits pledging support to Uddhav Thackeray-led faction and claimed the "fraud" is akin to another Telgi fake stamp paper scam.

The Mumbai Police recently registered an FIR against unidentified persons on charges of cheating and forgery after recovering more than 4,500 affidavits being prepared in support of the Thackeray-led faction, now called `Shiv Sena Uddhav Balasaheb Thackeray` party.
