Melaye had accused David of being behind an alleged assassination attempt on his life in April 2017 in Kogi.
But in a suit filed by the office of the attorney-general of the federation (AGF), the federal government said the police found out that Melaye’s claim was false.
The suit is before a high court of the Federal Capital Territory (FCT).
The senator is accused of deliberately giving false information to the police to frame Bello’s chief of staff as the mastermind of the alleged attempt to assassinate him.
Melaye is also accused of making a false statement of facts in a phone conversation with Mohammed Abubakar, son of the late Abubakar Audu, former governor of Kogi, with the intention of harming the reputation of Bello’s chief of staff.
The senator was at his country home at the time when gunmen numbering about 10 reportedly attacked him.
