Four teenagers investigated over attack on German MEP

Two of the suspects have been identified by their first names and first initial of their surname, as is common practice in Germany, as Quentin J, 17, who appeared at a police station in southern Dresden on Sunday accompanied by his mother, and Leander H, also 17.

On Sunday evening, Leander H was confronted with a search warrant by police at his home in the east of the city. All four addresses where the youths lived were searched by police, who gathered evidence at the scene as well as removing objects from the homes.

In a statement, the state prosecutor, Sabine Wylegalla, said: "The four accused are young men of German nationality aged 17 and 18 respectively. The investigation is ongoing and will take some time."

Thousands of people on Sunday took to the streets of several German cities, most notably Dresden and Berlin, to condemn the violent attack, amid an increase in the number of assaults on politicians in recent months, and a doubling of attacks since the 2019 European parliament elections, according to government data.

The attack has been roundly condemned by politicians across the political divide in Germany and the EU amid demands for an increase in both security for politicians and harsher penalties for perpetrators of attacks.

The motive for the attack remains unclear. None of the teenagers has so far spoken, according to police, who have said they are being investigated for grievous bodily harm. It has been widely reported that they had been drunk at the time of the attack.

As all four suspects are registered at a permanent address, they are not being taken into custody, although investigators said this could change once further circumstances were determined.

Speaking on Saturday, Nancy Faeser, the federal interior minister, blamed the far right for stoking a climate of violence with hate-filled rhetoric, including on social media.

She pledged to take "tough action and further preventative and protective measures", adding that a greater visible police presence was required on the ground at political events.

"We need more police presence on the ground, to protect democratic politicians at campaign stands and events," she told the Rheinische Post in an interview.

Other politicians, including Markus Söder, the head of Bavaria's Christian Social Union, specifically pointed the finger of blame at the far-right populist Alternative für Deutschland (AfD), which has been rising in the polls for the past year.

The co-chair of the Social Democrats, Saskia Esken, warned against playing down the attack on Ecke as a one-off act of wayward youths.

"It is very clear that this willingness to use violence hasn't come out of nowhere," Esken said at a solidarity rally on Sunday at the SPD state headquarters in Dresden. "This has to do with the seeds of social division and messages of contempt for democracy that come from the AfD and other rightwing extremists.

"In this regard, these people who have threatened to hunt us down, to clean up and even to clear out this country, also share responsibility for the social climate in which such acts are possible," she said, calling on wider society, as well as political parties, to condemn the attack.

The AfD's co-leader Alice Weidel condemned as "vile and irresponsible" what she said were attempts to exploit the attack on Ecke for political gain, saying that AfD politicians and party members were frequently attacked.

In Dresden and Berlin, participants at rallies held up placards reading: "No space for hate" and "Our democracy will not be intimidated."
