Mansoor al-Jamri, former editor-in-chief of Al-Wasat newspaper, says he and two other former top editors will answer the prosecutor's questions Monday.
Bahrain accuses Al-Wasat of running fabricated news reports and false pictures.
Al-Jamri denies the allegations. He and the two other editors stepped down last week to save the newspaper from a campaign to muzzle anti-government media.
Bahrain has sharply tightened Internet and media controls under military rule imposed last month, after weeks of protests against the Sunni monarchy.
