A court in Tanzania's largest city of Dar es Salaam has postponed a hearing in the case against top investigative journalist Erick Kabendera after the prosecution asked for more time to continue its investigation.
Mr Kabendera was arrested on 29 July and has been in custody since.
He is facing charges of money laundering, tax evasion and involvement in organised crime.
The journalist has not yet been asked to enter a plea and the charges are considered too serious for him to be granted bail.
The magistrate ordered that Mr Kabendera be arraigned in court on 30 August.
The manner of his arrest and detention has raised concern about media freedom in Tanzania, both locally and internationally.
Earlier this month, the US and UK condemned the handling of his case.
Mr Kabendera's lawyers say their client say is being targeted because of an article published in The Economist about the nation's president entitled: John Magufuli is bulldozing Tanzania’s freedom.
