The following is a summary of a Breitbart article:
Gangs of migrants in the German town of Essen have engaged in Cologne-style attacks at a Festival on Friday and Saturday, where police had received reports of at least ten incidents.
The police had made over seven arrests of migrants who groped and harassed several woman. Unbelievably, the suspects were detained and later released after being questioned. The migrants live in nearby asylum homes.
The attacks started after the performance of a musical group, when a pair of attackers molested a group of 18 year old girls and were subsequently apprehended by plain clothes police officers. The attacks took place in various parts of the city, with two particularly serious assaults happening on Friday.
In addition to the sex crimes, other festival-goers reported that the migrants had harassed them, pick-pocketed them, and were even violently attacked by them.
