A man has been arrested after assaulting Denmark's Prime Minister Mette Frederiksen in central Copenhagen on Friday evening.
The premier was "shocked by the incident," her office said, confirming that Frederiksen had been hit by a man on Copenhagen's Kultorvet square.
It was initially unclear whether Frederiksen, a Social Democrat, was injured in the attack.
One person has been arrested, Copenhagen police confirmed on X without providing details on the suspect's identity or a potential motive.
Over the past days, Frederiksen had been out and about to support the Social Democrats' top candidate in the European elections, Christel Schaldemose, including on Friday.
However, Schaldemose told Danish news agency Ritzau that the attack was not related to campaign activities.
Danish Defence Minister Troels Lund Poulsen called the assault "a shock."
"This is not Denmark," he wrote in a post on X. "We don't attack our prime minister."
The incident comes as millions of EU citizens are heading to the polls to elect a new European Parliament.
In a post on X, European Commission President Ursula von der Leyen condemned the attack on Frederiksen as a "despicable act which goes against everything we believe and fight for in Europe."
Addressing Frederiksen directly, she said: "I wish you strength and courage - I know you have plenty of both."
There has recently been a surge in violent attacks on politicians of all parties amid campaigning for the European Parliament elections, taking place June 6-9.
Slovakian Prime Minister Robert Fico was critically injured by several shots on May 15 when he stepped outside to join supporters after a government meeting in the small town of Handlová.
Authorities have described the crime as politically motivated. The shooter is in custody and has been charged with attempted murder.
In Germany, a number of politicans have been attacked while campaigning for the European elections, most notably social democratic lawmaker Matthias Ecke who was beaten and hospitalized in Dresden at the start of May.
