The federal government has filed two separate set of charges against Isah Misau, senator representing Bauchi central.
A set of charges were filed by the office of the attorney-general of the federation (AGF) at the federal high court, Abuja, and the other before the FCT high court.
The suits follow the disagreement between the senator and Ibrahim Idris, inspector-general of police (IGP).
The police had declared Misau a deserter after he accused the IGP of collecting money from police officers before they are posted.
He also accused Idris of collecting money from oil companies and banks where police officers are sent to provide security.
Misau is accused of forging false documents comprising affidavits and declaration of age he deposed to at the Bauchi state health management board and FCT high court.
He is said to have submitted these documents to the Independent National Electoral Commission (INEC) in 2011 and 2014 when he ran for public office.
The senator is also accused of making false statements that police officers pay N2.5 million to get special promotion and posting and also claiming that N10 billion is being received by Idris from oil companies and banks.
The offences are said to be contrary to section (1)(2)(c) of the miscellaneous offences Act Cap M17, laws of the federation of Nigeria, 2004 and punishable under the same section of the Act.
The suit against Misau is coming a few days after the senate set up an ad hoc committee to probe the senator’s claims against Idris.
