The letter by centre-left SPD mayor Dr. Sigrid Meierhofer to Maria Els, vice president of the government of Upper Bavaria, talks of an "explosive situation". It was leaked to the local newspaper and is part warning, part cry for help. "There has been an increasingly worsening situation in recent weeks around the registration centre Abrams," wrote the mayor.

Frau Meierhofer went on to argue that if no help was forthcoming in helping to defuse the situation the centre for 250 people could not continue operating. Around 150 of the residents are Africans, 80 percent of them unaccompanied young men. In the previous year it was mostly occupied by Syrian families. Mayor Meierhofer makes it plain that the current occupiers of the building have become "problematic" with frequent clashes. The mayor added that she is increasingly concerned about "public order and security." Curfews on migrants entering certain areas, like the spa park in town, have been implemented in the past few weeks.

There has been an increasingly worsening situation in recent weeks Frau Meierhofer

Police officers have responded to more incidents in the past six weeks in and around the centre than in the past 12 months put together. Deputy police chief Thomas Holzer said: "The blacks are in charge." He went on: "There are brawls, fights and property damage. The blacks occupy the best wi-fi places, choose who sleeps in what room. The situation is a problem for us and causes some concern. In September, we recorded a quarter of our annual operations." Repeat offenders at the centre have been moved to some of the other 11 facilities in the area, but the problems persist.

Local social media speaks gravely of sexual assaults of the worst kind taking place in the accommodation centre, but Holzer said he cannot confirm this. Frau Meierhofer explained in her letter that the complaints from locals were accumulating and that they were not from the far-right or other extremist groups. "They are expressing their trials and tribulations to us", she writes.
