HELSINKI (AP) — A Finnish court on Tuesday sentenced a 26-year-old man to six years and three months in prison for hacking tens of thousands of patient records at a private psychotherapy center and seeking ransom from some patients over the sensitive data.

The case that was initially revealed in October 2020, has caused outrage and shock in the Nordic nation, with a record number of people — about 24,000 — filing criminal complaints with police.

In February 2023, French police arrested well-known Finnish hacker Aleksanteri Kivimäki, who was living under a false identity near Paris and deported him to Finland. His trial ended last month.

The Länsi-Uusimaa District Court said Kivimäki was guilty of, among other things, an aggravated data breach, nearly 21,000 aggravated blackmail attempts and more than 9,200 aggravated disseminations of information infringing private life.
