HELSINKI: Finnish police said ‌on Thursday ​they have launched a criminal investigation into suspected breaches of environmental law at the construction site of a planned Google data centre in northern Finland.

The project ⁠is part of a plan announced last month by Alphabet's Google to invest $15 billion in artificial intelligence infrastructure in Finland, ‌which the US company described as its largest investment in Europe.

Authorities say Tuike ‌Finland, a subsidiary of Alphabet's Google, conducted ‌forest clearing and drainage at a planned ‌site in Muhos ‌before environmental impact assessments required under Finnish law had been ​completed.

"Based on ‌preliminary information, ​there have been ambiguities ⁠and shortcomings in the drainage and water management at the construction site of Tuike ​Finland ⁠Oy's data centre ⁠project," police said in a statement.

"The criminal investigation will examine, among other things, circumstances ⁠related to these issues," it added.

Finland's Supervisory Agency, which oversees environmental permits and assessments, on October 6 ordered Google to halt preparatory measures altering the environment ‌at Muhos as well as a separate site.

The company started ​the preparatory works based on its understanding of the approvals required under relevant legislation, Google has previously said.
