Police suspect former Jyväskylä City Councillor Teemu Torssonen of human trafficking, according to tabloid Ilta-Sanomat.
The suspected offences are related to Torssonen's relationship with his ex-spouse, as police believe the politician forced his former wife to work for his fisheries conservation organisation, among other tasks.
Police confirmed the suspected offence to IS, but declined to reveal the identity of the suspect. IS discovered Torssonen was the suspect in the case from other sources.
Torssonen rose to national prominence when he became one of the main suspects in the attempted murder of Finns Party aide Pekka Kataja in July 2020.
He was acquitted of the charges in February 2021.
Torssonen was first elected to Jyväskylä city council on the Finns Party ticket, but was soon expelled from the party and formed his own group.
The council took the unusual step in October 2020 of dismissing the entire city board due to a lack of confidence, and then immediately appointed a new board. This was done as a means of removing Torssonen from the board.
Torssonen made another, but unsuccessful, run for a council seat in 2021.
Later that year, the Central Finland District Court sentenced him to one year and five months' probation on charges of aggravated assault, a firearms offence and an illegal threat.
