 On February 1, 2015, analytical news program "Nothing Personal" reported that Rīgas Satiksme may be involved in a fraud scheme related to the company's procurement of detergents and other cleaning aids in 2013 and 2014, when plain water was supplied instead of the ordered nanotechnological detergents.In response to the report, Rīgas Satiksme set up a disciplinary investigative commission that performed an inquiry and reported not finding any violations in the procurement process.On December 14, 2017, four people were charged in what became infamously known as the "nanotechnology case" for a large-scale fraud causing 700 000 EUR loss to the company.
