German investigators have found nearly 400 cases of online hate speech related to last week’s killing of two police officers.
Officials in the western state of Rhineland-Palatinate said 102 of the 399 posts they were probing were “criminally relevant”.
Fifteen suspects had already been tracked down, they added on Monday.
Last Monday’s early morning shooting on a rural road in western Germany shocked the country.
Two men apparently opened fire with hunting weapons after being caught with poached wild animals in their van during a routine traffic stop. They were arrested hours after the attack.
“We will not accept people downright celebrating the cold-blooded killing of our two police colleagues and mocking the victims,” said the regional government’s interior minister, Roger Lewentz.
Late last week, a man was arrested over a video in which a masked speaker called for people to lure police officers onto country tracks to be shot.
