Investigative journalists Jacques Pauw and Pieter-Louis Myburgh, who have both written about alleged corrupt relationships involving President Jacob Zuma, have been summoned to a meeting at a police station.

In a letter to their lawyer on Thursday, seen by News24, Cluster Detective Co-ordinator of eThekwini Outer North, a Colonel 'R Govender' stated that the pair had been uncooperative.

"The tone of your letter is indicative that you have no intention to co-operate with the Police. In your previous emails to our office you promised [to] tender your full co-operation to the Police."

The letter was headlined "criminal investigations", along with their names.
