Finnish Foreign Minister Timo Sweeney has been subjected to an attempted attack while participating in a campaign to prepare for the April 14 parliamentary elections, local media reported.
An image published by the Finnish agency "Letikova" showed a local man and two guards holding him and preventing him from moving.
"The threat has been quickly addressed," wrote Sweeney, who is not running for the next election.
Witnesses told the media that a man wanted to beat the minister, who was participating in an election campaign in a market in Vantaa, about 30 km north of Helsinki.
The man arrested by the police was wearing the Odin Soldiers, an anti-immigrant group set up in 2015 to protect the people they regard as "Islamic intruders."
The minister belongs to the "Blue Reform" party, which is skeptical of the European Union and a member of the ruling coalition.
Sweeney, the founder of the "real Finnish" nationalist party, resigned from his party in 2017 after the election of Yossi Hala-Aho, who was convicted of racist remarks, as the party's successor.
Since last fall, Sweeney has been criticized for participating in an anti-abortion demonstration.
