One hundred police officers were injured and 54 people arrested in a single night in Frankfurt after Halloween riots that Hesse Interior Minister Roman Poseck said were "predominantly" carried out by people from a migrant background. One officer lost teeth after a stone struck him in the face. The rest suffered injuries from fireworks, bottles, and petrol bombs thrown continuously through the evening.

Police estimated they faced between 1,000 and 1,500 violent troublemakers at the height of the disturbances, according to Poseck, who spoke at a press conference on November 1. Brussels Signal reported that up to 1,300 officers were deployed and that police recorded 87 criminal complaints and carried out 366 identity checks. Poseck said 17 shops were damaged and five looted, among them a gun shop from which rioters seized two weapons, Die Welt reported.

The riots grew out of protests organised by the youth campaign group Gen Z regelt, which called demonstrations in around 30 German cities on October 31 over school funding and the cost of living. In Frankfurt, between 8,000 and 9,000 people marched largely peacefully during the day, German news agency dpa reported. Police dissolved the march at about 6:20 pm. After that, shop windows were smashed and barricades set alight in the city centre, public broadcaster ZDF reported.

Frankfurt police chief Stefan Müller said officers were attacked continuously and without restraint by groups of varying size. Firefighters and paramedics were also targeted. Police closed the Zeil, a kilometre-long shopping street and one of Germany's busiest, for the duration of the disturbances.

Poseck told his press conference: "This group of perpetrators was predominantly of migrant background. And we must address that as well. There can be no false taboos here." He noted that most of those detained held German nationality. The suspects ranged in age from 13 to 29. Poseck said only a small share of the rioters came from Frankfurt itself, with many travelling from elsewhere in Hesse and from neighbouring German states.

Federal Interior Minister Alexander Dobrindt drew a harder line. He blamed "violent left-wing groups and troublemakers from the migrant community" for hijacking peaceful afternoon demonstrations, according to Der Tagesspiegel and Bild. Dobrindt had warned on October 19 that left-wing extremists and migrant circles were joining forces against the democratic system. Violence spread across Germany the same night: Berlin recorded 27 injured officers and up to 56 detentions, Hamburg made 120 arrests, and Cologne saw clashes near the cathedral and central station, Informedclearly reported.

Frankfurt was the most severe flashpoint in Germany that night, but the continent-wide pattern runs deeper. In France on October 17 alone, nearly 2,400 people were arrested in a single day and close to 1,000 police officers and gendarmes were injured, according to Brussels Signal. An International Youth Strike is planned for November 20, with organisers saying it will include walkouts, blockades, and occupations across multiple EU member states.

Poseck pledged a special commission to study the Frankfurt events and said police would pay closer attention to migrant communities at future demonstrations. He added: "We cannot surrender the country to those who act with such violence against our police."
