Lööf was not the only person to react. "An absurd spectacle," said Rakel Churi to the national tabloid Aftonbladet.
"I was surprised, it felt inappropriate," said Churi, who is cultural editor of the local newspaper Sydsvenskan, after witnessing the event in Malmö on Tuesday. "Such small children aren't political beings."
The children were given baseball bats to attack the piñata, which was filled with money.
"Our slogan this year is that we must redistribute existing resources," said Minna Skans, one of the organisers and a member of the Left Party's youth branch, who remains unapologetic.
"Humour has always been a political tool," she told Aftonbladet. "It isn't a personal attack, but an attack against current political policies."
Left Party spokesperson Ted Bergdahl said the party is against all acts of violence.
"We understand if people took offence," he said.
"It's a shame they can't use their creativity for something creative, like new solutions to youth unemployment," Lööf responded on Thursday.
