A Nigerian newspaper says the country's federal police are detaining two of its journalists over a story it published about supposed plans by the office of the president to disrupt opposition parties.

Azubuike Ishiekwene, the group managing director of Leadership newspaper, told The Associated Press on Monday that officers continued to hold the two journalists without charges over the story. Ishiekwene said two other journalists earlier released by the police said officers told them the presidency wanted to know the source of their story.

Frank Mba, a federal police spokesman, did not immediately respond to requests for comment Monday night.

Leadership's story, published last week, cited a document it said came from the administration of President Goodluck Jonathan threatening the business interests of opposition leaders. The presidency denied the claim.
