Independent MP Rajesh Ranjan alias Pappu Yadav was arrested late Friday from his Patna home in connection with a 1995 forgery case under IPC Section 467.
Yadav initially refused to go with police, claiming they lacked an arrest warrant, before being taken into custody amid protests by supporters.
The MP alleged political targeting, saying the action was linked to his criticism of the Bihar government and recent law-and-order issues.
