According to The Guardian, Tensions rise in Germany over handling of mass sexual assaults in Cologne:
The events have since come to dominate German media, but following a barrage of complaints on social media that the New Year’s Eve events were deliberately under-reported amid fears they would encourage anti-immigrant sentiment, Germany’s public broadcaster, ZDF, was forced to apologise for its decision not to report on the attacks until Tuesday, four days after they had occurred.
Andreas Scheuer of the Christian Social Union, the Bavarian sister party of Angela Merkel’s conservative CDU, accused the media of exercising too much caution and forming a “cartel of silence”.
The same claim can be found in many other places.
We can't prove motivations, but we can measure media coverage and link it to publicly available information:
- Is it true that the Cologne events were not or almost not reported on in German media until the following Tuesday?
- Does the start of more significant covering fail to coincide with any significant new information which became available?
