Detective Inspector Henry Sostein Dowa, delivered the summons to the newspaper’s offices in Harare on Monday.
The police want to question Zimbabwe Independent Editor Constantine Chimakure and Farai Mutsaka, the newspaper’s former news editor, who wrote the story in August.
In the story headlined “Chihuri opposes electoral reforms” the newspaper disclosed that Chihuri demanded a reversal of sweeping electoral reforms agreed to by coalition government partners and suggested that police maintain a presence in polling stations as well as the postal voting system seen as aiding vote rigging.
In his story Mutsaka, a veteran journalist, who resigned from the newspaper last month quoted a letter written by Chihuri to the co-Home Affairs ministers, Kembo Mohadi and Theresa Makone in July protesting against the agreed electoral reforms.
Dowa reportedly told Chimakure during a meeting held Monday at the newspaper’s offices that the police were keen on knowing the source of the story.
The journalists are likely to report to Harare Central Police Station on Tuesday morning in the company of their lawyers.
Dowa is amongst senior police officers who are regularly linked with the arrest and harassment of rights and political activists.
